About 15 years, I found a voucher with well over $100 on it at
Milford. I ended up betting with it the rest of the matinee, and
then went back for the evening performance. If I recall, I bet
much heavier than I normally would, and made some more money.
On the other hand, I have lost a few vouchers that I did nothing about, so I probably came out even. For fear of losing one with a high balance, I will cash some out if I hit a big payoff.
