I&#x27;m kind of saddened with where the Sierra Club has ended up.  I&#x27;m very favorable to the idea of defending the environment, but those guys are  pretty stodgy in their ways.  For instance, their opposition to mountain biking has turned a large and growing number of people away from them and their message, which is sad, as it&#x27;s a group that has a lot in common.  Their opposition to density is even battier.
