I still like the idea of a pick six. If it were possible to make it mandatory with each adult admission ticket you received 5 different $1 (quick pick) pick 6, tickets. Just make the price of admission $5 more to cover the bets. If you wanted to, you could then exchange your "quick pick" tickets, for picks of your own at the betting window. That way every adult sitting in the stands would have a vested interest in the pick 6 and it would seed the pool.
