I haven't gone in years, but I was a regular in the early days.
First time was the 2nd GS Nats in 1982. There were about 50 cars, show was held in the Howard Johnsons parking lot. Drove my gold 66 GS from my college in Columbus, Ohio. Then in June, we drove out the the Car Craft Nats in Indy.
Took my replacement blue 66 GS in '83. Raced Lee Laursons red 65 GS 4speed car about 6 times. We ran fender-to- fender every run. Good times!
Drove the 4.11 geared Blue 66 a few times, my 79 Turbo Regal, then trailered the Blue car down twice after i got my 91 F150.
I went almost every year until my last year in 1993.
It's a long drive from here, a good 14 hours. The early date makes it difficult as well. lots to do on the farm in the spring.
I did make Jim Shiels' Buick picnic last year. Drove my 66 Special 600 miles r/t with the fresh Richmond 5 speed. Jimmy has the worlds largest collection of 66 GS's! Last I heard it was 12 cars! ;D
I attend Yardleys picnic every year, thats a good 25 minutes away!
I'm putting a red 66 GS together now that should be a good highway car. Hoping to make some more of these events in the future.
