Peter may be part fish and part bird.


He is an active scuba diver, and has spent time under water in most of the major seas and some of the best dive locations around the world.  This corresponds to Peter’s interest in traveling - he usually logs hundreds of thousands of miles a year flying for business and personal travel. Ask him about a recent trip, and he'll surely have one to tell you about.
