I know that the south side Irish has their Parade in Beverly last Sunday. And then there is a big parade in downtown Chicago and I would think it would be today but I don't know. There is a saying, everyone is Irish on St. Patrick's Day.
Oh yeah Rich Miller's Capitol Fax Blog was the first to post this video as well as other videos including one of a Chicago tradition. On St. Patrick's Day the river would be dyed green in commemoration. Cool isn't it.
