Border between Costa Rica and Panama. Panama: First nice asphalt road in I don't know how long. Colombia: Soldiers stopped to talk when I stopped at a store for a coke between Bogota and Medellin. They were not threatening at all, these guys are your friends on the highways here. Medellin has a metro train system similar to the El in Chicago, only here the hills are so steep that one branch is a cable tram. I rode up and down just to get a look at the city from up high. View from the cable car looking towards downtown. Medellin is about 2 million people. Weird sculptures outside the art museum in downtown Medellin. The bridge looking thing in the background is actually the tracks for the Metro.
