I went to all my DCs in NYC as a kid, too.
I remember having it at Aqueduct Racetrack one year, where the highlight of the day was when the water truck came out to sprinkle water on the dirt track.... the dirt that was newly wetted was darker, and by the time the truck made it around the track, it had dried up again and was lighter... and the truck went around...and around.. and around.... and around... and then I'd get smacked in the arm by my loving mother for not paying attention to the program in the 90 degree heat.... good grief.
We had one year, where the planes flew so low over the stadium that the speaker literally had to stop speaking while the plane flew over because it was so loud. Once when it started pouring rain, the most 'faithful' remained in their seats, simply opening up their umbrellas, while the people who still had brains went in under cover......
Those were the days.... NOT!
