Its gonna depend a lot on the soil type in the area. Bentonite is a major no go if it gets wet. You can barely walk in the stuff if it gets wet, you'll have two inches of it stuck to your boots. I learned to hunt pronghorn in the Shirley Basin, and there was rain coming we high tailed it out of there. You wont want to drive in a place like that at all if it's even damp. There's other places, like the Red Desert where it can get really bad when it's wet, but if you wait a bit after the storm the soil usually drains really fast. Your best bet is to just use common sense. If your gonna tear up the road really bad, it's gonna rut it all up and be a PITA for everyone that uses it after you even after it dries out, including you during hunting season. If you're hunting public, contact the regional office of whatever agency and they'll give you much more specific info than we can here. I like the idea of using a post to attach a come along or wench to in a bind, but keep in mind if you have to do that you're gonna have to do it a lot to get out, and at that rate you should have probably just parked in a good spot, walked, and used a good spotting scope to scout. Keep in mind there's always a lot of folds in the landscape that you can't see from the road, and often times that's where the pronghorn will be during the season, or even before. Let the road hunters push the animals to you. Often times, the animals get so habituated to the road hunters and seeing pressure from the same places over and over again that most of their focus is in those directions. Ive seen areas where the mule deer bed where they can watch the roads and obvious parking spots from a long ways away. That's how they survive. Make a big loop, which might be several miles, get behind the animals, let the other folks push the animals to you, and often times they'll never see what's coming. I shot a nice pronghorn a few years back on a walk in area by doing just that. All their focus was on the road hunters 600 or so yards away on the county road, and it allowed me to make a small move on pancake flat terrain to get in position when I was stuck with no move some 500 yds away for several hours. I shot that buck in bow range when the people on the county road stopped on the road to glass and the animals moved right towards me. Hunting pronghorn in heavily hunted areas is like a game of chess. If you get too aggressive, they're gone. They can cover a mile in no time. Sometimes it takes 3-4 hours to close those last few hundred yards, or for the animals to close the distance for you. Be patient, don't be afraid to crawl. If they see you crawling lay down and wait. Resist the urge to look up every minute. They'll usually go back about their business after a short while if you don't get too upright. Probably the most important thing, and I see people make this mistake all the time....don't park where they can see you and try to make a stalk, that'll end in failure 99 percent of the time, even if they're way out there.
