I just made a small — but significant — change to the site. Can you see it? If you think you know what it is, leave a hint in the comments, but don’t just blurt it out. More details and updates tomorrow; I’ve had a loo-oong two days and really need to sleep. In the meantime, check out these photos from today’s hike on the Billy Goat Trail near Great Falls on the Maryland side of the Potomac River.
(Update: Gee, was it that obvious?)
