I regularly pick up leaves that others have graciously raked and bagged for me! I use them in my vegetable and flower gardens after I've mowed them with the mulcher and put them in my compost system.

I am tempted to do the same with grass clippings in the summer, but I figure anyone who bags their grass clippings probably uses nasty chemicals on their lawn, so I pass them by. Too bad, because grass clippings and leaves make for some powerful compost!
