We don't all need to own our own lawnmower, tiller, weed whacker and gardening tools, do we?  We buy these things and keep our own because we think that's convenient, but how much harder would it be to walk down the street to a neighborhood tool shed where you could "check out" a well-maintained yard appliance for a few hours, and for much less than the cost of buying it yourself?  Sounds good, doesn't it?
