My favorite thing to do in fall is go on a Halloween hayride.
There is a lovely farm near us where they have a big pumpkin patch, cornmaze, and haunted hayrides that run all throughout October. It is certainly a party, the whole town shows up for the ghoulish fun! I consider this a yearly tradition for my friends and I, it just makes the approaching of Halloween so much more real. Shrieks and laughter fill the air as magic is uncovered there.
