My parents have been buying season tickets for the last...8-10 years now I think. They drive up from Vegas for each game. Every year they buy a bunch of extra season tickets just in case their kids that live up here can go. For the games that we can't all go to, they give them to some other cousins or friends that don't usually get to go. To them it's their way of spending family time together and doing something that we all enjoy. They usually head over to the game 1-2 hours early...which I just can't get myself to do. After the game I'm pretty sure they go back to Vegas and re-watch the entire game on DVR. That part to me is a bit...obsessive?? (sorry dad if you're reading this).
I go to as many games as I can, but with two little kids, it's hard to commit half a day to go. The night games are actually better because they're usually getting ready for bed when I leave for the game.
