Drag Strips and Antifreeze

I also have been running it for years and I race almost every weekend , a few weeks ago my over flow can was filled and a little dripped out on the burnout. Coming down the return road a track official that stays by the emergency crew at top end just came over and said " you dripped a little coolant " I said Thanks and I emptied my overflow can. They didn't yell or complain same thing when I blew a head gasket top end last year( I hardly put any coolant on the track ) But then again I have been racing there for over 30 years and they know me quite well , if it had been at another track in might have been a different story. Last year at another track I saw a track official walking the staging lanes looking under cars for leaks. A few years ago at the NED Bracket Finals the Sportsman Points Champ from my local track was staging for first round of the Race of Champions and dripped a tiny bit of coolant ( his thermostat housing cracked, he didn't know ) and they threw him out , he was able to fix it for regular eliminations however.
