I didn't see where OP stated his occupation, so that may make a difference.
NH has one of the country's most gun-friendly environments. NH also has one of the country's lowest unemployment rates. Almost no restrictions on anything you want to own. No sales or income tax, either! That means not only do you not have to pay those taxes, they aren't funding more and more bureaucrats to govern your every move. Liberal SOBs from the cities keep moving here, so a gun-friendly person like you would be quite welcome. The Free State Project chose NH as the most freedom-friendly state. Not every part of the state is this open, but NH is a place where you can have a 50 BMG range in your back yard.
Only drawback is that the winters can be long and harsh, especially for someone from California. OTOH, we don't have tornadoes, hurricanes are extremely rare, no earthquakes, no wildfires. The snow, ice, and cold may get old, but at least your house will likely still be there when you come home every day.
Here's a description of this part of NH that I wrote about 10 years ago:
The "Upper Valley", as this area is called, is the upper Connecticut River valley of the border towns of New Hampshire and Vermont. It's borders are rather vague, depending on who is describing it, but it generally runs from Bradford, VT/Orford, NH in the north, to Brattleboro, VT/Keene, NH in the south, and a few towns to the east and west of the river, centered around Lebanon/Claremont, NH and White River Junction/Windsor, VT. The area is also sometimes called the Twin State Valley, and the Windsor, VT to Springfield, VT area (the birthplace of the machine tool industry) is often called the Precision Valley.
The New Hampshire government has broken the state up into several tourist regions, such as "Seacoast" and "Lakes". This area is called the "Dartmouth-Lake Sunapee Region".
I'm an Upper Valley (Plainfield) native, dismayed at the flood, especially since the early 70s, of newcomers from the cities, with their City ways, City values, City attitudes, City politics, and City expectations. NH used to be a solid conservative Republican state (and so did Vermont, which has become even more liberalized than NH, with a flood of New Yorkers and the like). Now, New Hampshire has not only turned into a "Purple State" ,it's so bad no one even bothered to try to run as a Republican in the last couple elections for Cornish/Plainfield/Grantham State Representative. Sad, sad situation. Plainfield is worse than Cornish (which is why I moved back to Cornish, not Plainfield), and Grantham is even worse.
Did you know that, in the 1936 election, the only states to not vote for FDR were Vermont & Maine? That's how conservative northern New England was up into the 1950s, until the flatlanders started pouring in. Now, Vermont is one of the most "blue" states in the country, and NH is heading that way more every year.
Several years ago, the NH State Legislature finally succumbed to outside pressure and whining liberals, and changed our Civil Rights Day to Martin Luther King Day. We no longer have a holiday for George Washington's birthday or Abraham Lincoln's birthday or any other individual's birthday, but we now appease the blacks and the fawning liberals, who are so eager to demonstrate their "progressive, enlightened thinking", by creating a Martin Luther King holiday. MLK didn't do it alone; he had lots of help from both blacks and whites, including people who died in the struggle. For the MLK holiday dispute, NH certainly wasn't the "racist state", and wasn't even just the usual "obstinate state"; it was the only "correct state". But the liberal newcomers killed that. For 2007, NH has even passed a gay marriage bill, which our liberal Democrat Governor is eager to sign. The legislature also passed two pro-Second Amendment bills (just before the Democrats took over the NH Legislature), which the governor was eager to veto. Our new liberal Democrat Congressman is a New York Jew, just like Vermont's Bernie Sanders. For 2008, thanks in part to Bush's colossal blunders, the wretched ultra-liberal Jeanne Shaheen is now our US Senator. It's all enough to make me vomit.
The only benefit to the flood of flatlander liberals is that we finally got smoking banned in restaurants in NH. It's about time! We might even get a can/bottle deposit law to cut down on all the littering. I'm quite leery of the newcomers beginning attacks on our Second Amendment rights, though. Self-infatuated, ultra-liberal State Senator Peter Burling tried it March, 2007, although he got shot down big time.
I've also been known to say "There IS something to said for flatlanders". They "get it" on conservation and modernization matters more than the locals, and they are more open to change and improvements. The locals don't want to change ANYTHING and the flatlanders want to change EVERYTHING. There must be a reasonable middle ground.
I find it especially ironic that the liberals wail (and liberals are constantly wailing about something) about the Free State Project and how terrible and "unfair" it is, but even if every one of the Free State people actually moves here, it will be a drop in the bucket compared to the ongoing flood of liberals from the cities. The Free State Project goal is to get 20,000 libertarian-minded people to move to New Hampshire. But the Upper Valley alone has increased in population by probably that much in the last decade or two; and the increase has been mostly city liberals.
Southern NH, especially southeastern NH, is even worse; it's become nothing more than an extension of ultra-liberal Massachussetts (think fruitcakes like Ted Kennedy & John Kerry, extremist anti-gun politics, gay marriage, massive bureaucracy, a permit required to do ANYTHING, and "the only state to vote for McGovern"). When I was growing up here, the word "Massachusetts" in a sentence was usually followed by either "bastids" or "aholes". When I was a boy, I thought "Massachussettsbastards" was a word. "Massholes" is another common term in NH. Now, everything south of Concord might as well be MA, NY, CT, NJ or some other equally awful place, as people flood in from those places and try to recreate NH in the image of the nasty craphole they just left. It's just like how the people of Oregon a decade or two ago, and now Nevada, refer to the "Californication" of their state by the flood of Californians pouring into their state to liberalize and corrupt it. People in rural areas don't like city people, with their warped city values, moving into their nice country area and then setting out to "citify" it.
