UFC is always a great event and the card surpassed expectations. As always though, as with virtually any modern event, the entire place reeked of pot from the beginning to the end.
It may be legal now and I'm not against anyone smoking pot, but it isn't legal to be smoking anything in a public building. Even leaving the event, right outside the doors dozens of people are openly smoking right there, and no security or cops do anything about it - if they were smoking cigarettes they'd be fined or kicked out, it should be no different. Nobody wants to smell the equivalent of skunk BO for six hours but that's what an event in Vancouver is like.
