In my younger days I made money betting on horses, particularly harness horses.
I worked at the Meadows. Knew the drivers, trainers, even know the horses by sight.
But today, there's too much information available and it really makes it not worth the time or effort to collect and process the information.
$20 superfectas?
$6 trifectas?
$2.10 win tickets?
I can still make money but who wants to spend 6-8 hours researching for a $15 payout?
So now I bet big races for fun.
Other than some fantasy stuff (3-4 bucks a week) I don't do sports gambling and the fantasy stuff is just, again, for entertainment.
I'd rather not have a few hundred riding on whether or not a player goy laid last night.
