If you have ever driven across Canada, you know that Ontario goes on forever. Three days to drive across it.
Leo has planned lots of adventures for the kids along the way. One stop was in Sudbury at Science North -- a huge science centre. One of the interactive exhibits was a stone polishing station. The kids got to pick a rock and then go through 6 stages of polishing it. I think they spent an hour doing this and had a grand time.
They also got to pet the Science North beaver because they happend to be hanging around at feeding time. Evidently, its favourite treat is blueberries.
