Yes, that was the Dealer. The last time I was at his store he was thinking about retiring. So you must know Pat Patterson, the Mesa Schwinn dealer. I grew up hanging out at that shop and Pat's yougest son Ken and I were the same age and went to the same schools. Ken and his older brother took over the business when Pat passed away. Their store is no longer unfortunately.
Pat's first location in Mesa, late 50's.
