The East side is dry. 16” annual rainfall, but the problem is there’s nowhere decent to wheel. If we go W we get over to the wet side. I presume in summer the trails are pretty dry. Reiter was when I was over in July. I don’t know about Walker or others. If I go south into ID I think it stays dry. Looks like some decent wheelin in S Idaho, but that’s quite a drive.
It all depends. That one picture of my Jeep buried in the mud is July. The trails are still wet if we had a large snow fall the past winter. So even though we don't get the rain the wetside does we still have mud.
It was a dry year this summer for the wetside. That isn't normal. The trails in the central part of the state (best wheeling IMO) can get so dry and dusty in Aug & Sept that you have to wear a mask and googles to be able to run them. I'd rather deal with the mud but that is me.
