Visit Tallahassee's Online Event Calendar

http://www.visittallahassee.com/events/tallahassee_leon_county/

Surprisingly, Leon County's Tallahassee Visitor's Guide has a very decent calendar of events. Unfortunately, it's all on one flat page, so you simply have to scroll down and browse, but it includes a lot of interesting art shows and events that are fairly well hidden, in addition to many that are highly advertised.
