When Graem and I visited the Rideau River, we walked right across the frozen water at one point. That sort of thing always makes me nervous, even if there are tire tracks on the ice indicating that someone drove a vehicle that was (presumably) much heavier than me across safely... Maybe they just weakened the structural integrity of the ice!

We made it across safely and alive, and I even took time to gingerly crouch and examine this swirled bit of ice. When we lived in Edmonton, there was a glass shop nearby where we would always stop to admire (and occasionally buy) expensive glass bowls and sculptures that we couldn't really afford. This ice reminds me of one of those sculptures.
