CAW wagering is as much as 50% of the handle at many tracks. Tracks are in a tough spot. If they don't take CAW bets, their handle is minimal. If they do take it. you'll see odd payoffs including many 1/5 or even 1/9 shots. Give it a few more years and they will be doing 75% of the track's handle, for the tracks are losing more and more of the "racing fan bettor" each day.
