We don't have very many trees, but our neighbors do so we get a lot of their leaves in our yard. I've never really paid much attention to it until this year.
So the other day, when the kids and I got home, I ran over to the leaves and told the kids to run through them.
They were so excited. They would say "Ready...GO!" but then do nothing until I said "Ready...Go!" and then they would take off through the leaves. Then we would just do it over and over again.
