Most critters will run long before most people even see them, most times I'm ok with my HS model GB and a 4" brl. [.22lr] Your main worry are the 2 legged kind so what you're best with for that.
Leave the snakes alone and they will leave you alone. A telescopic walking stick/gun rest is more than enough to chase away most snakes. If you're bringing a dog there are companies/people that train them to avoid snakes, a shock collar and devenomed snakes, takes about an hour a couple off times and the dogs will always avoid them after. Not a big fan of shock collars, but I once sat up with a friend till his dog died of a snake bite, not fun.
