The Lawnmower Covenant

You may not now this but there is a divine influence on the gardening world.  It is said that:

When a gardener properly takes care of his lawn, allowing it to grow high, only cutting a third at a time, and takes care not to poison the earth with unnecessary fertilizers, pesticides, and herbicides that a sign will be given to bless the gardener's future efforts.

 Yes that rainbow stopped in my backyard right after I mowed.  Pretty neat, right? I'd better go find that pot o' gold!
