Although we've had some public parking lots in town starting to charge for MC parking. Thus far we've been fairly fortunate in the City and County of Honolulu, State of Hawaii.
My concern is having any County / State impose higher fees on bike registration, tacking on a tax surcharge on insurance policies, etc. etc. as a form of tax revenue (balancing budget) when my belief was to encourage a "greener" approach to transportation.
