Whenever the weather is nice enough I walk my children to school. It's about a half-mile - roughly 15 minutes at kids-walking-to-school speed.
I'm thankful because I can walk. And my children can walk. I'm thankful because we live in a neighborhood where I feel it is safe to walk. And because the walk is past a lovely creek where we can see Canada Geese and Mallard ducks pretty much year round - and sometimes an Egret or turtles. I'm thankful because it gives me a chance to talk to the kids about any variety of things.
And I'm also thankful that when it's rainy or very cold, I have a car, and can drive them to school.
