Speaking of Texans. We tried to drive into just the Sublette/Big Horn area one time and couldn't even get past the first dirt road as it had rained recently and we didn't have mud tires. 4wd didn't help at all. We were sliding all over the road and finally had to back out and hopefully not slide into the ditch. Meanwhile, one of the locals with a pickup and big knobby tires drove right past us like it was a paved road. We did get back there on another occasion when it was dry. Just something to think about if it has been raining.
