I always find it amusing how people are so concerned about hearing when they are on a bike, but not when they are in a motor vehicle. I guess when people are not protected by a steel cage they tend to be paranoid.

"Let us hope our weapons are never needed --but do not forget what the common people knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny. If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
