my friend Alan visited and then blogs about it.

My friend Alan has a cool bicycle blog – Cycling Weapon of Mass Destruction– and when he was in town a week or two ago, he happened to catch me at work, I sold him some rare bits and I even let him borrow my city bike for the day, to ride around Philadelphia.
His blog has cool track stuff, like Dura Ace 10 pitch, and follows cool auctions on Ebay, definitely worth a look.
