What do you wear to collect the Medal of Freedom from President Barack Obama? If you're Bob Dylan, a Rockmount Ranch Wear shirt. Looking at photos of the May 29 ceremony, Rockmount president Steve Weil saw that Dylan, a longtime fan of the snap-button Western shirts, was in a Rockmount solid white Pima cotton shirt with black diamond snaps No. 6940. And that wasn't Weil's only celebrity sighting last week:Peter Buck of REM also stopped by the store to do some shopping.
