Sorry I took so long, I had to get some sleep and then forgot.
Here's some lift info.
I'm not sure if it's enforced, we see rigs running around much taller around here.
As for wheeling areas, there all over the place, there's a bunch of trails right on the outskirts of the Tri Cities and then you got all kinds of forest service roads and such, it just takes some looking and maybe join a club in the area.
If ya wanna make a run up here we'd be happy to show you where we go.
