DragonCon

Every parade has bands and politicians, but this Labor Day extravaganza has bagpipers in steampunk gear and ruling-class representatives from Doctor Who and Game of Thrones. Plus, Muppets decked out as Stormtroopers, carousing pirates and wenches, superheroes and heroines galore, not to mention every element of the periodic table, marching (more or less) in proper formation.
