^^This is so true. They will lock the gates to the switchbacks if there is even a dusting of snow.Unfortunately the nps service is useless and will just tell you it's impassable until the stock AWD car can make it.
Correct, and I agree that Schafer is no more sketchy than mineral.I don't think there's a gate on Mineral, and I think Potash is always open too.
Which is weird, because of the two sets of switchbacks I'd be more nervous about the set into Mineral if it were icy, then about Schafer.
