Yes, we've been totally rained out and flooded. :E
We were spending the night in the city park of Montrose, SD on our way to Mt. Rushmore. We had crossed a bridge over a totally empty small river bed to get to the park. During the night it rained and rained - the sound on the roof of our trailer was quite comforting and we slept like babies. We were totally oblivious to what was happening outside. We woke in the morning to clear weather, but 6 inches of water covering the entire park *and* the bridge! We sloshed through the water to get to the TV and tried to start it thinking we would at least move to whatever higher ground we could find, but with all the wetness it wouldn't. We walked into town (crossing the bridge by using the side railings sort of like a sideways ladder) looking for an auto parts store. We found one and asked for wire drying spray - they said they didn't carry it - it never rains there.
We ended up just waiting it out for the water to recede some back into the river bed and dried the wires with a hair dryer. The worst part was the flood must have caused the potable water to become un-potable as I made lemonade and we were then very sick for many days. We'll never forget dragging our sick selves out of the TV to get a glimpse of the faces.
