Travel.  All together I have spent nearly a year of my life traveling and living outside of the U.S.  I have spent several months each in Portugal and Mexico, have visited nearly all of the countries in Europe, South America and Central America, and several nations in Africa, Asia and the Pacific.  Here are a few photos from recent trips (clockwise from left): touring the vineyards of Alsace, the harbor of Marseilles, a Korean meat market and with Professor Tito Cardoso e Cunha at the Bibliotheque Nationale in Paris.

Sailing. I never miss a chance to be near, on, or under, the water.  I started sailing and scuba diving as an undergraduate and, after a long hiatus, am back doing both.  Here is a picture of me behind the wheel of a J/105 (9 meters LWL) off of Long Beach. I own a vintage, 1977 Chrysler Buccaneer for sailing on local lakes, shown below.  This is a fairly large (18-foot) daysailer that carries a lot of sail. Boating off the Mediterranean coast of France.

Genealogy. As part of my research on family historians (described elsewhere on this site), I have investigated my own lineage. In contrast to my mother's parents (who were 20th century Norwegian immigrants), my father's line has been in the U.S. since the 1630s after coming from England. I discovered that the Case family settled in Southold, Long Island, New York originally, yet over the course of three centuries the younger members moved steadily westward in search of new farmland: Pennsylvania, Ohio, Indiana, Illinois, Missouri and Iowa (where my father was born). The path of these families is mapped state-by-state on genealogy websites, using 19th century census data. There is a Case family DNA project at http://www.familytreedna.com/public/CaseProject/ that hopes to connect and disambiguate the various lines of the family. The pursuit of this information is a fascinating hobby, recently made much easier by the Internet and the efforts of local governments and family historians everywhere. Here is an illustration of research accomplished "the old way," in this case a family history hand-typed by a distant cousin, following years of visits to, and correspondence with, relatives and county records offices.

Coin-Collecting. Related to my research on hobbyists (described elsewhere on this site), I have been collecting coins since age 6.  I collect mostly silver and gold coins from around the world, but chiefly Canadian.  Here are perhaps the largest and smallest coins in a collection that numbers in the thousands:  A silver 20 balboas (4.1 troy ounces!) from Panama, and a Liberian $10 gold coin.
