I, Ldub, Jim, Kenny and others have traditionally held a fall run at Gilbert (Iron Range OHV Recreation Area, to be precise). You need the OHV sticker (available at the same places you get tabs), otherwise entrance is free. They will also test your exhaust noise; basically if you have a functioning muffler you will pass.

I'd be up for either weekend so far.
