Gettysburg Daily features every day (and I mean every day) large photos and discussion of some minutiae of the Gettysburg battlefield. Topics covered include: Dinosaur footprints on the battlefield, artillery shells lodged in local buildings, battlefield panoramas, witness trees, and rampant development. Whoever does the site recently started an award program: "The Sickles," awarded for the dumbest thing done on the battlefield in the past year. The award is named after General Daniel Sickles.
