I figure the previous place bet almost covers the 2 losing wagers prior so that can ony be a good thing.

heres a way to invest the spare $5 tonight.
Buy a SANDOWN Park Box Challenge.
Put the $5 on Box 5
I don't know the Odds available on TAB , but there is an agency offering $6.50
I have it rated as a $4 Chance.

For those unfamiliar with Box Challenge , it is similar to a Jockey Challenge , but instead of using a Jockey to gain points, the actual Box Numbers are used.
