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.
