Edits of  April  moving refs to References section   Ive moved all of the remaining references from the notes to the References section To make for a readable alphbetical list Ive used the publisher as the author where no specific author is given Some of the dates eg California Museum  are a bit contrived and for a couple of others I cant figure out what to use for dates There are issues with some of the references   The link for the reference for Sierra Club b is broken  The link for the Wilderness Society reference points only to the home page so it doesnt support the statement to which it is attached  The reference for Sarkowski shows a date of  my copy of that book  second printing shows a date of  The LOC database shows the same date and doesnt show a second edition  I cant find anything about Goldbloom  all hits from a Google search for Philly Art Walks ultimately point to this article Consequently I have no idea what sort of reference it is or how to format it Moreover it seems pretty shaky with respect to WPV  Ive included comments before each of these references
