- Jun 2, 2007There is going to be a US Power Squadran GPS class at the Moss Landing
Harbor Masters office confrence room on June 16th. I have seen the
book and it is woth more than they are asking for the class and it will
teach you how to use the GPS units which would be valuable in both
navigation, land and sea as well as Geocaching. You can find
information at the following reference site.
