Despite the association of trainspotting with the tracks left in the arm of a heroin user, which may have its origin in the 1996 movie of that name, the word is used in England to describe a person obsessed to the point of mania with the trivial. Trainspotters haunt railway platforms in England, notebook in hand, writing down the numbers of trains that roll through. Then they gather and compare lifetime lists. South Florida trainspotters covet a spot on 15th Street under the I-95 overpass, west of the Pompano State Farmer's Market. Four train lines rumble down the tracks -- Florida East Coast Railroad, Tri-Rail, Amtrak, and CSX Corp. So you can see a damn fine assortment. But if you decide to head over in pursuit of the trivial, take a few words of advice from big brother New Times: Don't let the monkey on your back.
