The guys that cut limestone in Monroe county and thereabouts were stonecutters, so calling them cutters made sense if stonies or stoners had been ruled out by the film makers. I spent a couple of years at IU and then came back to Bloomington a bit later for a few years, including when the film was shot. Had only heard ‘stonies’ used in reference to some locals. I took up cycling while living there - wonderful area for cycling - and was very interested in Breaking Away. Got married and moved to Atlanta for 8 years. The Breaking Away TV show was shot in North Georgia - hilarious to see shots of kudzu in some of the shows scenes!
