Re: that look
Paul I've had the same happen to me, a couple of years ago on July 4 my wife was working so having the day off I decided to do some riding to some other places I haven't been on a bike. I stopped at a supper market, parked next to the front door and went in to get something to drink. When I returned outside a retired gentleman was looking very closely at my bike, the first things he asked was where did I get and how old was it. When I said its a bicycle and I built it he paused for a second then shook my hand and said "that's cool ".
Your results may not be the same,Greg
