Snow Valley is just past Running Springs a few miles, on the way to Big Bear. Near the Green Vally lake cutoff.
Thanks, Joe, for the pointers, now I really get it!
There are THREE ways up there. I was looking at the two, those being 1) to/from Hesperia and 2) to/from Lucerne Valley. Now I see the 3) Hwy. 30 route. Duh!
The folks are stopped after where the 30 and the from-Hesperia 18 merge, from what I can tell.
