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

Worst storm was in Council Bluffs IA. We set up in the local casino camping area. We went across the river to have dinner with friends and came back to a flood. This happened in June 2014 during the College World Series. We were told the following day that it happens every year. The picture was after 12 hours of steady pumping. The MH on either side of us had water in their basements.

Well, so much for the picture!!
