So I showed up this morning at a Potomac Pedalers Touring Club "C" ride in lovely horse farm country just east of the Skyline ridge. Tom Roberson led the ride (thanks, Tom, it was lovely!). This category is folks who love riding, but aren't necessarily bike nuts. There were maybe 15 - 20 folks, all on modern bikes, except Tom's KOF Ramoullet and my '65 Schwinn Paramount. I wasn't quite sure how to respond when a lovely lass with a great smile looked at the bike, and said, "Wow! Those Tubes are thin..." She was refering to the main triangle, not the tires. Sic transit gloria.
