We had a pot bust here in Montgomery County, Maryland, USA recently. Police installed surveillance cameras near a site in a local park where there was a healthy crop of pot coming along. The "gardener" soon appeared, and in the video shown on local TV he is seen apparently watering his crop. It's more interesting than that. When interviewed, the culprit told reporters that he was a student at a local college trying to better himself. He was impressively articulate and seemed not at all distressed at his predicament. His course of study: the criminal justice system! I guess he's now acquiring some highly detailed experience. This gives new meaning to "field work" and "what's your field of specialization?" Years ago I had a co-worker who out of the blue went out of his way to befriend me when he learned that I was into gardening. The only thing he seemed to be interested in was growing plants under lights. He seemed to know an awful lot about this - more than I ever thought I needed to know. He seemed to know a lot about reflective wall coverings, the intensities of various light sources, energy costs...When I said pot and he said pot, we were not talking about the same thing. Jim McKenney Montgomery County, Maryland, USA, USDA zone 7, where local lore has it that George Washington grew it (strictly for fiber of course) and, until the Civil Conservation Corps "eradicated" it in the '30s, it was purportedly common in the Potomac Valley.
