fun on ice (near the ice)

      The World Ice Skating championships are happening in Boston, at the Garden. I'm not a big fan of figure skating, I don't really like competitions, and I hadn't been to the Garden since it was re-done (decades?) ago, but having people come from around the world intrigued me (this is true of the marathon, too.  I also watch that).  After some thought, I picked the ice dancing short program to attend, and bought the lowest price ticket (30 dollars)  It was mid-day yesterday.  Ice dancing doesn't include the big jumps that competitive figure skating does, so there is not much chance of competitors falling.  I hate seeing people fall.  There are required lifts, but they're a bit like aerials in swing dancing, rather than the crotch-holding overhead lifts that happen in pairs ice skating.
Thirty couples:  warm-ups plus three-minute routines plus judging plus some Zamboni visits took about four and a half hours.  It slipped by pretty easily.  Mostly I was kind of zoning out, in a "that's nice" kind of way.  All of them are supposed to be precise about matching the tempo of the music with their routines, but it turned out that the actual music choices mattered a lot to me, as did some of the costuming choices.  After a couple of hours, I got to the point of being able to see who was doing a better job, so that by the time we got to the top level (the people with the lowest qualifying scores went first), I could see how they were better than the first bunches, but the routine I liked best ended up in fifth place.  Apparently it wasn't their first time performing it - I found a version on youtube:

     During the required waltz part of the routines, every couple came quite close to the edges.  Clearly, for international competition, the rinks must be a standardized size.  But in this case, it's a hockey rink.  Did the hockey people and the figure skating people get together at some point to agree upon dimensions?
