ya that sucks i hate driving that far.

There is NOWHERE legal besides The Cliffs. Cliff's isn't really that far depending on where you are in the ****ty(oops, city). Cliff's is muddy.. and it can be EXTREMELY muddy. But compared to all the other legal wheeling spots.....

badlands in attica in isnt to bad. 20 a day. about 70 miles from me. a good trip for a day of fun!

The badlands is very fun and very affordable :) Well worth the trip for anyone really. I am only a few miles from it but. You will enjoy it if you make it there sometime :)
