The US Constitution is a living and breathing document which means no more or no less than the meaning we choose to give it at any one day or time. The meaning of meaning, the meaning of power and politics is fluid and plastic and is not bound by Old Testament "word is law" bias. If Blackhawk wants to ban cyclists, I say good for them. Their interpretation of constitutional rights and privileges is as living and breathing as anyone else. And anyone who tries to make the argument that "living and breathing" is just another meaning for "judicial usurpation" is itching for a fight and will be banned from watching Fox News for all Eternity.
