And then there is good luck...
Years ago we took the kids to Vegas. We got offered a bump in St. Louis with an offer of a free room for the nite plus a couple hundred per person. The kids didn't want to take the bump so I had to bribe them with $50 each. We got in town about 10 hours later. My youngest (she was 5 or 6) wanted to play Keno at the Dunes where we were having lunch. Of course she won $100. She was in town 10 minutes and already was $150 up! She still has thet kind of luck.
