I know it started in 1986. My first time there was 1990 when i moved to NJ from VT.
Originally I believe it was BIG-A (could be wrong) and lots of stuff from CVS as well. Back then is was much BIGGER than it is now (80 to 90 plus rides as compared to 65 to 70 now). They used a lot more foot print (parking lot space) back then! Big-A had all/most of there BIG stuff back then there: (Mack Music Express, Mack Discoteck, Swiss Bobs, Hully Gully, Looping Start looping coaster, and Huss Rainbow to name some....) CVS was playing with Conklin at the Westchester County Fair at Yonkers raceway back then and had some of those ride in with Big-A.
Wade had it for 1 year in 1996. And yes, that is where he took delivery of his White Water Flume (now gone from the show) and I watched them remove if from the shipping containers and set it up for hours. Wade had 2 of their 3 units there. Wished they would have done more then 1 year...
Believe Strates had it for 2, may be 3 years. Forget the years they had it. Had all the Huss pieces (Enterprise, Pirate, Rainbow and Top Spin) plus the Sky Diver, Sky Wheel and a coaster and flume too....
I know over the years Reithoffer has had pieces in there several times. The last time was several years back and the Huss Tornado was there.
I also remember one year Blue Grass Shows had there Soreni and Moser Extacy there. Was new back then and looked great. The back Drop was integrated into the tub load trailer.
Others i recall seeing there were a Chance Falling Star and a Double Shock. Big-A's Looping Star single loop coaster. And the Space Wheels... Yes, the Space Wheels played there one year with Big-A. Was the year of one of the World Cup Scoccer events that took place there and the midway was moved to the back parking lots.
