Re: Afton Canyon 2WD??
I've found that in that general area your best luck for 2WD travel is in the spring after rain has tamped down the sand (but definitely not when still wet). As more people travel over it, the sand gets really beat up on some of the trails (the other end was horrible once when I was there, like dune sand). And the whoops can make it worse.
The only way to know is to go out there (although that's not feasible until the fall; you might try after the first big rains).
