Stop in for a cup of coffee

The farmers round here like using those annoying "Hoops", a portable pop up green house kinda thing. I hope they haven't got their crop covered up yet. Not just a back yard affair, talking 160 acres worth. Raised beds, drip systems, the whole 9 yards. Only thing I didn't see on the last visit was the security detail.
They must be legal then if they don't have a thug patrol guarding the goods.
