Side benefit: they make great conversation starters with your neighbors, babysitters, repairmen, social workers...
Yup, I can picture it now...
Me:
[raking lawn, notices new neighbor Blast walking my way, pulling a super long tape measure]
Hi! Welcome to the neighborhood! Watchya doing there? Gonna put in some new sprinklers?
Blast:
Hi! People call me Blast. Y'know, like "Blast zone." Heh-heh.
Sprinklers? Naw. Just figuring out fields of fire. And I want to make sure all of my long guns are zeroed for the relevant distances from my front windows over there. The ones with the shooting slits, that is, not the ones I have completely sealed up with bricks.
[Then eyes narrow and a smile appears on his face] Say there...I like your rake...
