Guys:
Thanks a bunch for the information & advice. I am close enough to the Toronto market that it might attract a buyer if I flog it there for $50. I have no intentions of putting the time and effort into building this frame into a rideable bike but perhaps some Miyata enthusiast will pick it up to have as a project. I'll strip the crummy wheels & seat off it to make it easy to mail and I'll post it on Craigslist, Kijiji (or eBay) and see if I can unload the frame to someone who knows its potential. Too bad its so small.
I already have a much bigger Miyata that I use around town, one of the Miyata Elevation bikes, and it is the veritable felines fundament for shopping & doing short hops on. I have other bikes, lots of them, but the Elevation is such a delight in town & virtually theft-proof, unlike my other stuff.

Thanks again.
