One summer, we had a job cutting the grass for several hookers who rented a house around the corner from our local middle school. We never confirmed they were hookers, but they voluntarily paid three times our normal mowing rate, and guys in suits often "visited" via a side entrance. Their unkempt yard had been attracting unwanted attention from the neighbors, and we slaved over their tangle of crabgrass, weeds and briars for a week before the place looked as well-tended as the other houses on the block. We netted $150, which was more than enough for an Atari. If we'd been true entrepreneurs, we'd have invested in a Dixie Chopper, had they been invented back then. We could have cornered the suburban whorehouse landscaping market.
