Many thanks to all who helped out.
We went to the game last night, and it went well. Thanks to the info you provided my son and I were able to understand what was going on, and we had a good time.
We arrived early and paid too much money for a hot dog, hamburger, fries and drinks (as with any sporting event). We walked around the arena and saw the sights, he was very impressed by the rink. Our seats were good, I can only describe them as being on about the 35-yard line (in football terms), about mid-way up the lower section in a fairly small arena (seats about 11,000).
We bought a program, and the vendor pointed out we had won a prize. We had to go to a booth to collect a $25 gift certificate to a restaurant, which was pretty nice. Then we bought t-shirts, and my son wanted to put his on right away.
We enjoyed watching the teams warm up, and I had the time to explain what little I knew of the rules. Once the action started he was following it well. We were able to keep an eye on the puck, which I think is much easier in person than on television. We were both surprised by how physical the game can get, a lot of checking and such. He became a little bored with the lack of scoring, but once our team scored a goal he saw how exciting it was, with the horns and crowd cheering, he appreciated the build up of emotion.
There were 2 fights, the first of which got pretty bloody. I think my son was so shocked by the fact that these guys were actually fighting, not just pushing and shoving, that he couldn't appreciate it. On the way home, he asked why they would fight if they are just going to get put in "time out" for it. I explained that they know it is against the rules, but sometimes they just get so excited they forget. A good lesson, as I could note that this was no excuse, and they were still punished.
The break after the first period was 18 minutes. We stayed in our seats, as I knew that there was usually some goofy entertainment. The first of this was a mini-Newlywed Game, which did not impress the adults and did nothing for the kids. But then they made the husbands run around doing chores, sweeping up pucks, picking up dirty laundry, etc. At least that involvled action instead of talking. Then came the zamboni, which we enjoyed. A mini-blimp flew around dropping prizes too (coupons for free rounds of golf, but my son still wanted to catch one and win, although none came near us.)
Although it was getting late, I told him we would stay until the end of the second period. This seemed much faster than the first, with fewer game stoppages and a little more extended action. Another fight, less bloody than the first. Our team scored again. My son was asking about icing and offsides, and about "saves" when the goalie made a good stop. I was able to explain well enough for him. There were a few times where there were penalties for reasons that escaped me, but the action kept moving before we could dwell on it. We were enjoying seeing the goalies make some great saves, and my son was getting into cheering this too, so I was glad he was not only focused on scoring. He also understood the concept of power play, and the excitement when our team would try to take advantage of the opportunity.
We left with the score 2-0, and I later learned our team won 3-0.
A good time, and maybe something we will do every once in a while, but I don't think it will become a regular thing. The cost is one issue, but of course I won't have to buy t-shirts, programs, and overpriced junk food every time. The tickets were priced at $16 (although ours were free), which seemed a bit much for AA, and in fact the arena was only about a third full. Of course, it was a Tuesday night, perhaps the weekends are a little busier.
Thanks again to everyone who helped us enjoy and understand the experience.
