With environmental concerns about transportation centered on everything from air pollution to oil drilling, you would think states would want to encourage the use of bicycles wherever possible.  So it was more than a bit strange when a California legislator recently proposed the state slap a $7 fee on the purchase of two-wheelers.  The idea is to facilitate more bicycle recycling, but according to the Pacific Research Institute, old bicycles are not a disposal problem since they are quickly snapped up for their parts, or refurbished by local thrift stores.  If the $7 fee was added to the already hefty sales tax of 8%, it would increase the cost of many bicycles by 10%, and would  thus, environmentally, be peddling in the wrong direction.
