I traveled with 8 other people when I was in Central America from 1994-1995. CDs were obviously popular by then but they didn't travel as well as cassettes, so we all brought Walkmans on the trip. Once we got settled in Nicaragua we tossed all our cassettes into a cardboard box and created a tape exchange. The picture above reminded me of that. It was a good way to "discover" new music while we were cut off from the rest of the world.
