is there any casinos accept sports gambling outside of nevada?

In the US, I know of Delaware Park casino, but it doesn't have normal wagers, only sucker-bets from what I recall (multi-team teasers with high vig). Better off finding a bookie or betting on a site like 5dimes. If you like betting underdogs, bet on Bovada until they limit your account (compare their lines to any other book's and you'll see why I say that).

Outside of the US, I'm sure there are plenty of places. I've been to Aruba, whose casinos had normal sportsbetting.
