I'll Give a few of the ranchers a bug in their ear whilst I'm running iron this winter. I'll do some checking in a couple of spots, are you wanting to do some sight seeing or just rat blasting? It really makes no difference in the maggot murdering, just where you'd base yourself out of. I guess my first recommendation wouldbe Casper, only cause I know the area and some ranchers that are anti rat and real pro blastin.
You're not far from the Rattlesnake Range, the last set of hills in the Big Horns, rat blast in the AM...Go for a picnic in the mountains, and rat blast in the PM, and stop off at the VFW in Mills for a victory party over the murderous Huns.
Next day same thing cept maybe take all dirt roads around to Kaycee, and have lunch in Chris Ledoux's hometown, and go back by I25 and stop off along the way for another round of defending the good people from the hordes of vermin.
It can be as much of what you wanna do, I will probally only be able to guide you around for a weekend and maybe an extra day. But I think the places I have in mind will keep you as busy as you wanna be, and if you want to camp, I'm pretty sure I got one that will go for it.
