I once went to an outdoor wedding in New York State, up near the Canadian border. About 10 miles from the Dannemora prison actually. It was outdoors, the priest wore those reflective sun glasses that CIA agents wear in the movies and he rode a motorcycle. It was a beautiful wedding but very hot. Make sure any venue you choose has some shade!
The reception was pretty exciting when a number of the wedding party rode their motorcycles into the VFW hall.
