When we lived in our "country" home when the kids were young we had 3 acres, mostly naturally wooded and we were at the end of a long private dirt road. Never raked the first leaf. The little bit of grass I mowed around the house I just mowed the leaves along with the grass. Ahhh....Nature.
Can't do that now, but thankfully our tiny yard takes about 30 minutes to mow and edge.
