Right on. I grew up with events like these and miss them dearly, especially Riverfest. Things like the Rib Cook-Off, Taste of Cleveland can be done in Public Square instead of the Amphitheatre.
As for the roads, Can traffic be limited to only the buses cutting through and leaving the cars to go around the outside? Or can something be done similar to that of the "traffic circle" in D.C., or in this case square?
