To bad about your broken arm! I was at the Fox Valley HS but didn't have a stuffed animal on my rear fender. I do have a support deal with Moose though. I live in Rockton, just north of Rockford. No places to ride up here, all have been shut down, except for some private tracks. There is always Byron Motosports park, but most of the woods are off limits now. Nothing in Wis either, except for Black River and Neilsville (just north of Black River).
Your friend that has the land by the river, did he ever let a club run an enduro through there? We use to run an enduro in that area and used land all over that area. Or does he ride trials? A couple of friends said they rode on some land by the Kishwaukee river a while ago.
I'm sure Jeff can get you a nice bike, I heard he's good with those KDX's! (yes I am joking, I race against Jeff at all the IL enduros)
