Yep, today was the day to take Gwyneth to her first NHL game (what other big game did you think I was talking about?) . ;)
She had fun, although it was probably a period too long for her, and she didn't mind that we were in the "Eagle's nest" (at least there's no-one behind us).
She liked the cheering, but not when it got too loud. Strangely at one point she started shouting "Come on America", which was very even handed given that the game was between two American teams - the Washington Capitals and the New York Islanders. The game ended up tied 1-1 and going into overtime and finally a penalty shootout, with the Capitals winning 1-0 after 3 shots each.
She said that she'd like to go back and see another game, so we'll probably do that. :)
