We used to buy/sell @ Super Chevy IRP during the late 1980's to late early 2000's.We'd come down I-65 from Chicago always,but for a few years later on,we took the more rural US 41 south to I-74.We'd stop @ the gas stations along that route to gas up before entering the show,and guys also on their way to the show,would be peeking/picking through our trucks & trailer while they too were gassing up.
We made some mind boggling sales & trades along the way,compared to today.
