Sounds like you are alarmingly close to Smudge. It might be time to move?
Lots of Gassers in the N. IL, but they are of the trials type. Keytime no longer sells GG, but they can still get parts.
Doesn't Rockford has some sand pit off of Hwy 20 that's open to riding? You might look into joining Forest City Riders, they have some club ground and get lots of riding in, when setting up the enduro and dual sport. One of there members has a GG.
