Beard, you suffered the worst Big Mac Attack I've ever heard of! Damn that's scary! Please report back on your H-18's aftermath.
I had many a fun and hairy time out there when I lived in the Boulder-Denver area, but never one approaching that extreme... DAY-UM!
Even in "normal" times it's foolish to head to McConaughy without at least 4 good sand screws. On at least 2 occasions that I remember, those of us who "screwed our boats to the beach" had a great 3-day weekend, and those who didn't had broken boats and went home p*ssed.
Still, that NIGHT WIND can be great fun when there's a full moon, and someone to man the shore lights!
