I visited the Brockton Cycle Center, and handed them a poster for the SE Mass Italian Bike Day, in Taunton. They've bought into the Guzzi/Aprilia package; two big signs out front, plenty of bikes, and some t-shirts on hand.
I hope they do well. The strip they're on has everything else; BMW, Ducati, Japanese, and Harley.
Guzzi might fit in.
As an aside, they greeted me warmly, but it immediately cooled when I told them I wasn't looking for a new bike.
