This is the first time I see Waterloo not covered by snow. When I was here in December last year, I took the wrong exit from the building and found what I thought was a large untouched field of snow. After too much brain activity during the day, I wasn't in the mood to figure out how the key-card works. I decided I could manage 3 inches white fluffy stuff on the pavement. After some steps however, I stumbled down an invisible edge, and stood more than knee-deep in snow. I was cursing whoever constructed this stupid yard.
However, today I solved the mystery of the annoying edge: it was the pool! (see photo below).
