THE ART GUYS TO START UNRAVELING This is the route the Art Guys say they will be taking tomorrow morning when they stage the 5th of the yearlong series of monthly celebratory stunts they’re calling “12 Events:” Titling this one “A Length of String,” Jack Massing and Michael Galbreth will unwind a spool of thread they’ve had sitting around since 1983 while walking along White Oak Bayou between W. Tidwell and T.C. Jester, just north of the Loop, and then they’ll turn around . . . and wind it back up. Last month, you’ll remember, they donned tuxedos and conducted the sounds of the Ship Channel from the Santa Anna Capture Site in Pasadena. [Art Guys; previously on Swamplot] Map: Art Guys
