So I did have a problem on the way back. I shut my engine off at the gate and then it wouldn't start. I think my distributor or coil got wet from snow, and I had to wait for something to dry out. But I have the '79 dizzy with the vented cap, so I'm not sure how snow fluff would have gotten into something enough to cause a problem.
And then it happened one more time before I hightailed it back down the hill to get home.
Anybody have any ideas where I should check first?
