The only good thing about getting old is I got to see the Forum, Stadium, Maple Leaf Gardens and had season tix in the old Garden for 10 years. Those buildings were special, I only saw one game at the Stadium but what an amazing place to see a game, The Forum was special, it was a hockey rink, not a multi use facility, if you went to another event there (I Saw Iron Maiden there as well as many Habs games) it still felt like it was the Canadiens rink not just an arena. Maple Leaf gardens was hot and cramped, I'm a big guy and while Fenway has small seats they seem like Lazy boy loungers compared to MLG. I got to see one game at the current MSG back in the mid 80's and the reputation of the crowd was more than lived up to. Joe Louis was OK, what I remember most was the awful traffic at the exit to the rink, at least I got my Probert wear clothing but the building felt very generic, much like most of the new arenas. Concourse was very crowded with plenty of Little Ceaser's stands making it even more cramped.
The Garden was special, cramped, hot, not great sight lines ( my seats were in the 4th row of the balcony behind the net, until the league moved the net out a few feet in the late 80's I never saw the back of the cage) and I miss it so much, the "new" garden has none of the atmosphere of the old place, to me that isn't a good thing.
I miss those old rinks, old AHL and junior building as well, they had a feel to them that the new rinks, while very nice with amenities cannot match. Probably the only rink left with that feel is the Colisée de Laval, I'm not sure when the Canadiens move their AHL team to Laval if they will be playing in this rink or a new one, hopefully the Colisee stays the same.
