Replying to Cinco de mayo, tour around lake erie

so, me and a few buds are rollin from columbus ohio up through Windsor, Toronto, and then back around Erie and the falls next weekend. basically, we are all 20, and have been wantin to go on a random road trip. do those places go off pretty heavy for the 5th?

also, anything cool you guys would recommend, places to see other than the obvious ones, good bars or clubs to check out. should be nice weather wise, any cool swim holes up around the north end of Erie?
