I have vivid memories of that San Diego light rail. I spent several hours once at a freight yard in San Ysidro, waiting for a trailer to be found down in Tijuana, so I rode the rail up to San Diego. I must've chosen the wrong time, because as soon as the car arrived at the border, it was swarmed by about 1000 "green card" employess, all dressed in various fast-food and hotel uniforms. I didn't get on that train, but was ready for the next! Geez, even New Yorkers on the subway aren't that eager to get on!
