Big Deal longride. The NPS will always error on the side of caution. In two days everything will be open and this will be a non story. Obviously you have never lived for any length of time in the west. Flash flooding occurs from time to time and roads close. National Parks can close from forest fires, flooding, avalanches etc. I was once on a forest fire where we had 100 degree weather one day flash floods the next and the only way out was by air. If you (longride) would ever venture out of Chicago you might learn something.
