One day, a forman for a North Dakota landscaping crew was in this
store (I was just passing through). Periodically, he would shout
outside "Green side up." I started talking to him about whatever. He
kept going outside and shouting "Green side up." Finally, after about
one hour, I asked him about "Green side up." He replied "If I don't
remind them, they will plant the sod green side down"
