My best friend who is building a house in his backyard in Berkeley, and there by definition has the patience of Jesus when it comes to authority abused, had his feathers slightly ruffled when driving home from home depot with a shower door. He had to lower the back seat and so his teenage daughter was sitting in the back without a seatbelt when the cop pulled him over for no apparent reason. The fine was $500 for a minor not wearing a seatbelt. and the cop waited around until he saw the kid get on the bus (with herMom). The bus has no seatbelts, but thats a gvmnt vehicle.
Also, Starchild I applaud your enthusiasm about getting the posters out there. even though we have to reign it in sometimes.
On your problems with promotion and advertising, I think you throw the baby out with the bathwater. Freedom of expression is an essential liberty, including the freedom to present people with new ideas and new services. Like all human activities, thetools are sometimes if not often used to promote unhealthy or destructive, or aesthetically displeasing behaviors. However, sometimes the tools promote valuable knowledge, and are even quite creative in and of themselves. If you choose to join the Luddites in rejecting many forms of free market promotion, that is your choice, I don't see why we should cower to the desires of a few Luddites. when working to spread our nearly invisible ideas.
