Thanks folks. Steve B - fair point, I admit I may have been projecting a bit with that. dendawg - thanks, point on winter debris appreciated. I don't really have a reason to be in that area in the immediate future but if I do I'll try to track down one of the rangers for a bit more clarity. There are times I don't mind taking a few liberties, but under the circumstances it doesn't make sense (to me) to be "that guy". I'm sure the park folks are dealing with enough. If I get more I'll post it unless someone beats me to it.
