Okay, one, Newcombs does not like large groups all at once, it cramps business unless EVERYONE eats or buys so there is that.
Two, trying to turn around a bunch of cars at the closure will be rather tricky, not that it can't be done, there is a camp ground there but it's still rather tricky.
Three, The trip down 138 is about as fun as watching rocks fuck.
Eighty miles, give or take.
There are other routes too. Really I guess it would depend on where you all want to end up at, they's good food errywhere.
