In planning their Hawai'ian vacation from California, the O'Tool family decided to schedule in a family photo session.  They also wanted a backdrop a bit unique to the islands, since they do have nice beaches in California as well.  How about a lava rock shoreline?  This is even fairly unique to the Big Island in particular, as the other islands in the chain have lost a lot of their lava shoreline to sandy beaches over the years....many, many, many years.
