If you are like me and love the National Parks, but hate the crowds, you might appreciate A Night Under the Stars. It’s a look at when people are spending the night the most in each national park. It’s pretty interesting to see when each park is most popular (and by extension, which periods should be low population but still nice to visit). Found via the inimitable Kottke.
