I’ve started yet another web site. This one’s for people wanting to buy & sell Bicycles. It’s centered in the Portland area right now, but if I get enough activity, I may consider re-vamping it for other areas too. Check out Bikes For Sale at BikeAds.org

It took me forever to find the link to do it, but here it is:

This link will produce an error if you don’t already have Google personalized search enabled. But if you do, and are logged in to your google account, it should let you remove it. Worked for me, but ymmv.
