Haha, nice to meet a fellow Capital-region dweller. It was a private seller who responded to an ad I placed.
I'll probably use the Shimano wheels to tool around for a while. The guy told me that the tubies currently mounted are near 10 years old. The rubber looks like it's about to peel off, so when I go down to the shop to see about the brake drilling, I'll probably get them to mount a new set of tires for now. Still seeking advice on what to do with the wheels.
