Thanks for posting the link to the video. I only attended Pine Brook occasionally, but went at least 1 or 2 times a year from June 1976 until it closed in the late 80's. 1st time was an EWS rain out so I shot up there that Friday night. I was also there for the last show in the fall of 1988 or 89. Never saw a bad show there; they always had good racing.
When I was a young kid, I believe it was the first year of Pine Brook, they had 2 TQ midget drivers put on a 10 lap exibition race at Old Bridge on the inner 1/5 mile. The announcer, believe it was Nat Kleinfield, introduced that these cars and drivers run every Friday night at Pine Brook. Unfortunately about half was thru the exibition, one driver nailed the boards on the frontretch and rolled it, sustaining a broken arm in the process. I never recalled his name but I am quite sure he raced again after that.
