It can be fun thats for sure. Not so fun when your tires don't quite get the job done in the sloppy stuff though. My poor old 33's were no match for the benonite clay. Within minutes I had 4 brown slicks that no amount of wheelspin could clear out. This left me more than stuck in the bottom of a gulley I slid (almost rolled) into.
My buddy with a 3/4 6.2 burb lifted 6" on 35's came to my rescue. Being the one who was stuck, I hooked up the winch and he pulled me out of the hole I was stuck in to only pull me into a giant field of more mud. He pulled right out without any problems and started making his way for the road. Once I realized I was stuck again (which took all of about 10 seconds!) I had to call him on his cell again to come get me. Another yank to solid ground and I was free and got the heck out of there...
PMI is a good test site to run your rig on after you make some changes before you hit the real stuff. Plus if you make your way to the southwest of the area you get a pretty good view of the Pueblo Reserviour and Arkansas river. Heck I've even seen some dude out there in the summer with a ragged old K20 (every body panel a different color) and an old slide in camper out there on the highest bluffs to the south camping on the weekend. If he can make it with that old tank with a house on it's back, just about anybody here can.
