20+ College club hockey games
1 High School game
innumerable C-League games
I used to be obsessed with the Blues and Brett Hull in the 90s. They played a regular season exhibition game in the Richfield Coliseum versus the Whalers, and I was there. Brett Hull got into a fight. Best non-baseball sports event I’ve ever been to!
I’ve not been to another. But every time I go to a minor-league hockey game, I always think “that was fun. I should go to more hockey games.”
None, as sadly, I can’t afford it. If I could, I’d be there all the time to root for my Pens. (Seriously, the prices have gotten outrageous)
We’ve been going to a lot of Wild games. Started by getting them through various charity auctions then started buying them from co-workers with season tickets.
Went in with some friends to split season tickets 4-ways for next season.
Saw the Rangers beat the Caps, 3-2, at MSG on the day Liberace died. My father got two tickets from his office somehow.
I don’t live in or near an NHL city (well, I live kinda near one but it’s not near enough for me to want to travel to it just for hockey games) but when I was in the navy I once went to an L.A. Kings game (it was a regular season game, as I recall, and I have no memory of their opponents that night). That’s my one.
Couple hundred over the years…as a So-Cal, I root for the Kings and Ducks, but head-to-head, I always root for the Kings since I started watching back in the late 80s when Bernie Nichols was a rookie. Yelled for our team down in the tunnels between periods at the “Fabulous” Forum…Gretzky, Robitaille, Kurri, Blake, McSorely, etc. and then onto the Staples Center…love watching all the belligerent East Coast fans blow hundreds on tickets, beers and grub, only to go home losers in the end.
Also watched the Ducks at the Arrowhead Ponda Center over the years as well, even saw Selanne (as a Winnipeg Jet) shred his achillies’ heel at the Pond…loved watching Kariya and Selanne pairing up and lighting the lamp early and often.
Hockey is definitely the definitive live sport to watch…hands down. When you watch 60 minutes of hockey…YOU ACTUALLY WATCH 60 MINUTES OF ACTION…even more so if there are some “disputes”. 
One. But I didn’t have a choice.
Boston Garden - Hundreds
Fleet Center/TD Garden - one
Great Western Forum (Los Angeles) - two
Chicago Stadium - one
Buffalo Aud - one
Montreal Forum - five
Le Colisee (Quebec) - two
Hartford Civic Center - two
Brendan Byrne Areana (Meadowlands) - one
Madison Square Garden - one
Lotta games in buildings no longer standing.
Season tickets for the Caps since 2009 and I go to about 30 per season.
Zero, unless you count a preseason game between St. Louis and Detroit in Peoria, IL in the mid-1980s.
I don’t like hockey anymore, so I was relieved that Chicago’s team got eliminated the other night. I was getting sick of hearing about them from coworkers, news media, etc. Not only that, but when they win the championship and have a parade, the commuter train prohibits alcohol for the day. Now I can drink alcohol on the Metra whenever I damn well please. Fortunately I was away last year on the day of the parade (I was in Tampa to visit friends and see a Kesha concert), but I don’t have any Kesha concerts to run away to this time around.
