Looks like you had fun, and I surely don't want to yell at you but I am going to just offer some words of advice.
Trespassing is a BIG no no. Wheeling in places where you're not supposed to be, is bad juju for the whole sport. Not to mention, if you go to the wrong place farmer John is likely to take a pot shot at ya!
Google "Off Road Park Illinois" you'll probably find places that are closer than you think to go and stomp in the mud.
Check with your local Forest Service office or whatever you have up there for where you can go legally.
Please... enjoy your Jeep, but wheel responsibly and respectfully.
