Good Lord .... a small world. I was in that building around 2002 / 2003. We pulled a few bikes out it at the time. One I missed because we could just not get it off the first floor as it was just toooo damn dangerous, floor boards & joists rotten, was a Triumph 200 Cub with the snow tracks on the rear & skis where the front wheel would have been. This was a kit you could buy back in the late 50's / early 60's.
later ... ray
