Curious what made you give it up? Lack of scaleability? Or tougher to do back in US?
A combination of all of this. At the time I had the perfect set up so it worked out great. Basically, the sports book was in the back of the sports bar and it was like a club house.
Daily routine was, wake up go diving or play golf, grab lunch, head to the club house. Start pouring over the sport sheets, racing forms, etc. start playing the different tracks as they opened. Drink. Hopefully hit a few races, then line up the sports wagers for that night.
Hit the beach or resort, drink some more. Hopefully meet chicks. Set up night plans. Go home siesta. Wake up back to sports book, place nigt sports bets, play some more OTB, then dinner. If chicks were involved, try to get laid. If not, back to sports book and play some more.
Gamble with the other degenerates over pool, dominoes, backgammon etc. bed.
As you can tell, not a healthy lifestyle. I gained about 30lbs that year. But I think the major difference was that gambling was more ingrained in the culture there (Mexico) than here in the US. That lifestyle there was revered if you were successful, people here might call you a scumbag.
Also, very cheap to live there. A grand a week no taxes and u lived like a king. Didn't pay tourist prices for anything and were treated like a local so people would hook you up with shit.
Honestly, the thought never occurred to me to continue on that path when returning to the states. I rarely bet on sports these days and do the occasional horse betting. Do well usually with the exception of the track I frequent the most, Saratoga.
Can't win anything there as its the track known as the "graveyard of champions".
