I'm pretty sure the last sports game I went to was a Phoenix Suns preseason game in 2015. Going to live events is fun but the cost of them and seemingly always getting seated by someone annoying often makes me just want to watch comfortably from home.
I have been to a fair share of Diamondbacks games over the years, and my wife and I also used to like to go to Phoenix Mercury games because you can get awesome seats for very cheap. We went to a postseason game last time the Mercury won the title and it was affordable.
i have also been to a handful of Arizona Rattlers games and one Coyotes game but I've never been a fan of anything but basketball and baseball. Never seen the Cardinals.
The Suns also host a free scrimmage most years up in Flagstaff at the end of their training camp, and my wife and I like to make a day trip to go up north and see that. Unfortunately this year they are having the game at night and we don't want to be driving back to Phoenix late with our son so that stinks.
Also, one great thing about living in Phoenix is Spring Training. I have been to more of those games than I can count and it's awesome if you're a baseball fan to be able to see so many teams and games for very very cheap.
