This year’s PCC travel class changed from two islands to one.  The focus was upon aquaculture, and the multiple ways in which Hawaiians sustained themselves  and their leaders in ancient times.  The first adventure was to find the  four aquaculture “ponds” that were documented historically, and then to interpret their use.  This was followed by visits to other  archaeological areas, including abandoned villages and petroglyph sites that  aren’t discussed in the usual literature.  Afternoons were free time, which included everything from paddle boarding to relaxing under a palm tree.
