One of the girls' favorite fall pass times was making leaf piles--before the land scapers came and took them all away--and jumping into them. One day I had about ten kids in my yard.
In CA we don't have quite as many trees with leaves that fall...in the fall. But we are fortunate enough to have one in our own front yard.
The kids can jump in the leaves when they fall...until the land scapers take them away.
