Doonesbury by Garry Trudeau for February 08, 1972
B.D.: Dear mom and dad, while I'm waiting for the next wave of commies to attack, I thought I'd drop you a quick line. I arrived in Vietnam yesterday and I must say, I love it! I'm stationed at firebase Bundy in the Delta and I've got my own bunker and machine gun!! Can you imagine?! Well, have to run now...much love, B.D.
