This is the first of 3 "Cruisin The Gut" shows scheduled for 2004. I went to the last one in 2003 - it was very cool. Here's their press release:

"Come on out to the 4th annual 'Cruisin' The Gut' in downtown Lansing! This Classic Car Show features 1979 and older models of cars and trucks both parked and 'cruisin the gut'. Last year there were over 1000 cars at this event and it is one of the top 10 shows in Michigan. Nothing beats seeing these beauties motoring down Washington Avenue. Future dates are July 17th and September 18th."
