I've been putting in bits on unused pockets of land here and there. Blackberries on the neighbor's land behind his corn field, where he never goes. A downed oak tree got the shiitakes plugs. Rhubarb looks like an innocuous something and is good early in the year.

Planting row crops is just asking for theft. Things that don't look like food are great. Leaf lettuce in the front planter will get overlooked every time.
