I retired from the Smithsonian Institution in Washington, DC in 2011. I had a great career there, and currently do a lot of volunteer work for the National Park Service all over the country, but mostly in the western US. My wife and I are avid hikers and outdoors people. I'm into caving, backpacking, kayaking, xc skiing, etc., but also enjoy cultural activities and trying new things. We both love to travel and I've been fortunate to have traveled to all 50 states and numerous countries on 5 continents.
