LOL I might be in St. Igance instead of going to the down river cruise. And no the down river cruise is not in Detroit either. it's south of Detroit. Not surewhich cities are involved in it.
All the details are in the link below, but the cruise is on Fort Street and travels through parts of Lincoln Park, Southgate, Wyandotte and Riverview. Officially the cruise is on 06/24, however last year it was fairly packed on Friday night (06/23).
