Elk City (U90) has one of the more unusual runways I've landed on. It's shaped like a banana and perched on the side of a hill. There is a 30 degee difference between runway ends (runways 14 and 35). It definitely makes for an interesting landing experience.
If you're camping at Moose Creek or Johnson Creek, this is a good breakfast flight. The local cafe is about a 5 minute walk down the hill and the food is good.
