Skating at Nathan Phillips Square

About a block and a half away from my office, in front of Toronto's City Hall, is the Nathan Phillips Square skating rink. If I wasn't feeling craptacular from a crummy cold (try saying that five times fast) it might look fun. Thinking perhaps I should bring my skates to the office and get some exercise at lunch time one of these days. Doesn't seem to be very crowded on a work day.
