Despite several hundred very scenic pictures from the High Sierras and along the John Muir Trail, despite more than 100 pictures from Switzerland and Finland, and despite dozens of pictures of perhaps the cutest dog on Earth, this picture taken of me at the NASA Johnson Space Center posing in a silly touristy photo thingie is the most popular picture of mine on Flickr, with nearly twice as many views as the second most popular picture.
I am at a complete loss as to why this is the case.
