"You expect the crowds to go over and watch them come in," Tom Pfeiffelmann, of the Star Line Ferry, told the Traverse City (Mich.) Record Eagle. "This year, it just hasn't produced the crowds." Advertisement Pfeiffelmann said the resort island was packed as usual over the Fourth of July weekend but crowds have been sparse since the holiday. The number of vehicles using the Mackinac Bridge is down 2 percent from this time last July. Mackinac Island is Michigan's No. 1 tourist destination. Some business owners that depend on tourism blame high gasoline prices and Michigan's slow economy for the drop off in summer traffic.
