There's not much new material being added to this site as my primary interest has been development of Twain's Geography.  I've been reading through Gary Scharnhorst's massive three volume biography of Mark Twain, "The Life of Mark Twain", The Early Years , The Middle Years and The Final Years, while incorporating bits of geographic and socio-cultural interest.  Also, for some time now I've been incorporating the entries from David Fears' "Mark Twain Day By Day", courtesy of the Center for Mark Twain Studies where David Fears had generously donated his works.  Most of the pages on Twain's Geography have a feedback form and I try to encourage readers to comment on and/or enlighten me on the subject of that page.  This does not require any registration on the site but it does require a valid email address.
