The Madison convention and visitors bureau lists almost everything. You might also want to check out the Isthmus site, which is a link to a great local source of information on things to do.

Our favorite event is the Dane County Farmers' Market, which goes from 6:30 am to around noon every Saturday. It is one of the very best farmers' markets in the country, with a huge selection things made by the people who sell it to you. The farmers sell from stands arranged all around the state capitol building, which is also something to see!
