What's the worst storm you have been in while camping?

Hurricane Irene in 2011. We were at Scussett Beach on Cape Cod and had to evacuate. Ended up riding it out @ Circle CG in Bellingham, MA. They gave us an open spot without trees. We had our Monaco Executive at the time, which at 45,000lbs was not bothered at all by the winds.

It was an exciting day though, to say the least. Getting out of the CG a couple of days later was an event as wires and trees were down everywhere.
