I know this one was mentioned... Flemington Speedway in NJ.. Originally was dirt then they paved it... Now, it is a Walmart!! I was very sad last time I drove by! When we ran there a carnival was across the street. I would always do one of those sand art things, one year I dropped it in the women's bathroom at the speedway. All of the colorful sand spilled everywhere! From what I remember, the bathroom's weren't nice anyway! I at least made it colorful!
