I have a crappie mounted on my wall that I caught at Lake Oolagah. I believe that was the same storm that spawned a tornado in Stillwater while I was attending a summer session at OSU. It went right over the dorm and took out part of the roof on a building on campus.
Several years later I went through another one in the same campground. Not quite as bad but still bad. It was in the afternoon. I just drove to the Will Rogers Memorial in Claremore and stayed there until it was over.
When I got back, I was surprised that my tent was still up.
