REM, the 30-year-old rock band, has just announced its demise. REM defined my adolescence and young adulthood, their songs punctuated various coming-of-age events in my life. I used REM's Nightswimming as inspiration for my short piece about playing in hotsprings in Colombia. You can hear snippets of the classic song in the audio version called "Poohsticks at Coconuco." The story also appears in a slightly different form in the online magazine Hippocampus.
