The kids have always enjoyed Lessard Park. It's a little park in west Toronto on top of the ravine that leads down to Etienne Brule Park by the Humber River near Old Mill. Now that I think of it, I used to enjoy Lessard Park as a kid as well.
It's got a big field and baseball diamond, and they've just torn down what I thought was a pretty good playground and replaced it with a brand new one.
We dropped by at the end of our walk last night to see how the construction was going. There was enough in place that the kids could start breaking in the new funnery.
