First: you asked, okay? I'm not tooting my horn, kapich?
IF, I win, I donate my winnings to a certain local charity. The first few times, I checked with a person in charge to make sure that charity was receiving the money. They were.
I didn't check after the first two times. Any of the times after that, I just assumed they received the checks. And trust me, I've lost way more times than I've won.
