Three Forks, MT is always a favorite lunch flight from West Yellowstone.   The views while flying along the mountains in the Madison Valley are fantastic.
  Once in Three Forks we usually stop in for a bite at the Sacagawea Hotel (the oldest building in town), if the restaurant is open.   If there's time, a visit to the town's museum is a must.   If you're a fan of really old, cool gadgets, you'll love it.
