I've heard plenty of people talk about the fact that the books only accept cash payments for sports betting, but I always wonder how that could be possible with big-time bettors (like Voulgaris, Walters, etc) laying down hundreds of thousands at a time? My experience is only with online sportsbooks but I'm planning to move to Vegas in the near future and wondering if there are other options. Sorry if I should already know the answer to this one, but I don't.
