At my first host position I set up and all was well until the first good rain. My site was in a slight hole that filled with water up to about 4" deep. It drained off quickly after the rain quit, but while it was still 4" deep I needed to go somewhere. I went down my steps and stepped on my new ground mat. It was a new mat and I didn't know that it floated. I didn't fall, but came darn close to it. Falling in that "lake" would have not made my day.
