Sorry about the vehicle troubles, a real pain no doubt.
We were in SD in mid June, had the best PD shoot EVER. We had dogs galore, yes we were on a ‘reservation’. No adverse issues.
I will pass a secret, ‘Google Earth’. Once zoomed in one can easily see the bare spots around the PD holes and mounds. The GE images and then reality once at the location were always accurate for us. One spot we walked 1.8 miles in to get to my favorite honey hole.
The plan is to go back next June, after I reload all the cases.
