That sound is magnified about 100 times when you are there in person, and though I don't live around the Ice Rink, it sounds shattering to those that do. (Hat tip to a blog reader for the video.)
You know those Christmas trees that are being thrown away around the property? Particularly the Christmas tree "hill" at the 20 St. Loop? I just don't understand how some dog owners lack the awareness or courtesy to NOT let their dogs piss on those trees. I see dog owners even head there on purpose to let their fidos do their thing. Some worker is going to have to pick up those urine-dripping and smelling trees, but that doesn't matter to these dog owners. Yes, most dog owners are responsible, but others lack something between their ears.
