A Wonketeer writes to note that bike upon which John Kerry perched for pix yesterday, is well, really expensive.We're shocked. You mean a guy with five homes doesn't ride a Schwinn?Still, we had no idea how expensive it was.He is shown riding a Serotta, a small, high quality, custom bike builder whose frames start at $1495.00 for the frame ONLY and top out at a whopping $4,995.00 for the frame ONLY. Add $1,000.00 for tires, gears, pedals, fancy shoes, Boston College shirt etc.Am I being petty? Sure, but come on, a 'man of the people' dropping $3,000.00 on a bicycle?Think...
