Look at what was on the cover of the National Geographic magazine on the month/year I was born. I'm in the process of my moving my collection of NGM that dates back to 1955 that was started by good, old grandpa. Alas, there's a hiatus from the early '80ies to 1997, when I subscribed again. It's hard not to get sidetracked browsing each issue. This, together with the aviation bug and a genetic wanderlust, is the best inheritance I've got from him.
