Ironically, secession is about the most American thing we could do at this point. I enjoyed the following quote from this page on redstatesecession.org:

To quote James Madison in Federalist 39, each State is “a sovereign body, independent of all others, and only to be bound [in the Union] by its own voluntary act.” To deny this principle is to deny the most foundational idea of American law—that governments derive “their just powers from the Consent of the Governed.” If the States cannot peacefully secede, then they are in a Union held together by coercion, not by consent. Clearly, this was not the Founders’ intention. Furthermore, because there is no prohibition of secession in the U.S. Constitution, it is a right that the States reserve in accordance with the Tenth Amendment.
