I came out of the grocery store a year or two back, and there, leaning up against all the shopping carts, was a gold Raleigh Professional, early 70's model, near mint condition. Looked to be a 58 cm frame. Not locked or anything.
I walked right by it. Didn't even think to hang out and asked the owner if he wanted to sell it... or ... or ...
No, honestly, I didn't. I walked on. It was only later that the full potential of the situation presented itself.
