Coppergate Fly-in
The Coppergate Fly-in is a well established annual event and bills itself as the largest fly-in in the western states.
It is small when judged against the likes of Oshkosh and Sun 'n Fun in Florida but, judging by some 300 light aircraft seen in a few hours on the final day, it certainly has its merits if you are within 500 miles or so; local, as the Americans would say.
