As a Scotsman, my understanding of today is that St. Patrick drove the snakes our of Ireland to make it safe for Guinness. Today it’s a day where the young, young at heart and leprechauns can join together in the celebration of Irish heritage and perhaps tip a pint or two at their local Irish pub. Dogs and even horses aren’t left out of the wearin’ o’ the green. It’s an especially big deal in Detroit, home to a big St. Paddy’s Day Parade and the dapperest Irish web site in Michigan. Of course Detroit doesn’t take it to the extreme levels that our Windy City neighbors do.
