I've been meaning to post on this subject for a while now but I keep getting sidetracked.
The last time I was at the track there was a relatively young fella with an iPad in hand and he was furiously punting away via various sites...from what he told me the NSW & WA TAB's as well as Betfair. My how things have changed. He sat there in the grandstand most of the day and seemed to be betting like there was no tomorrow.
