This weekend is the last time you'll be able to catch Walter Putrycz, flanked by fidders above, playing John Burroughs, the famous naturalist, at the Open Eye Theater in Margaretville. "Pepacton," the theater's multimedia tribute to one of Roxbury's most famous sons, is showing tonight and tomorrow at 7pm and Sunday at 3pm. For more info about the show, see its listing in our calendar. Photo contributed by Amie Brockway Henson.
