Not the most you ever won, but your first big score?
Mine was in 95 or 96. I bet my last $5 on what I thought was 2 exactas at Detroit Race Course on a self betting machine. I got the tickets and it said Arlington. Obviously I hit the wrong track. I look at the screen and Arlington isn't going off for 20 minutes. Better yet, the horse I keyed in my 2 exactas was 40-1. I was about 20 and really was going to throw the ticket on the floor and just leave. In retrospect, I hope I would have left w/ the ticket in pocket and just checked the results later.
Anyway I stayed and watched the race. I got the exacta on both tickets and got a little over $600.
