You'd be surprised. In general, you never collect enough $$ to make the money really worthwhile for people, anyways... we had $50 buy-in and prizes of $90 for 2nd and $270 for 1st and even at those amounts, noone is trying to win to make the cash. It's all about the bragging rights. So just the idea that there is a prize to go for gives guys motivation. The amount that you do: $20, $50, whatever... isn't really all that crucial.
Also, one rule that I put down but haven't enforced yet, is that whoever finishes last has to play treasurer next year. Now that is a penalty.
0-3 to 4-3. Worst choke in the history of baseball. Enough said.
