The SCA is the Society for Creative Anachronism - people trying to re-create Renaissance, Medieval and earlier time periods.... events are kind of like going to a Renaissance festival, but there are no "tourists" - everyone there must dress the part.
If you're into fencing, check out www.sca.org - fighting, fencing, medieval archery and siege weapons play a large part of most events.
My favorite annual event, and a really cool website is www.pennsic.net. The Pennsic War takes place north of Pittsburgh PA every August for 2 weeks - camping, huge battles, merchants, classes, and nightly carousing, often augmented by homemade beer, wine, and mead.
People come from all over the world.
Anyways, cool - I am an artist, and collect fossils, too. What types of fossils do you collect?
