Saturday is a casual day at Belvidere. The Charger convention and late model vehicle show is not very big, around 50 cars total. The vendors are there and odds and ends of other vintage Mopars come by.
It used to be better on Saturday as there was a late afternoon Mopar cruise with a BBQ sponsored by a local CDJR dealer, but that ended 4 or 5 years ago.
Megaparts has always set up in one of the buildings on the fairgrounds.
The show on Sunday is much bigger, 300-400 cars and all the vendors etc.
