I generally use at Xmas and at the carnivals.
One only needs a Couple of 80 - 100/1 winners to cover any losses.
You need at least $20 as a minimum price and small $10 bets.
Small bank of $5000 should suffice with this one.

It relies heavily on that Secret Form Factor PL or as some cynics call it PA.
