get out the front, watch and see what the big bets are being put on, that what i do!
tho have seen a dew big bets go on from different people, ie a few grand, put my £10 and lost!
or get involved in the 3 way combo things inside with the tote, ie pick 5 2 and 6 in that order and any order 50p each bet so £3, can give real good odds as in 100s to 1, basically a bit of a lottery.
