Looking to waste a few hours today? Neither were we, but it happened anyway after we got blissfully sucked into Square America, a website of endless photos from the first 3/4 of the 20th century. Photos of roads, photos of what was on television, photos of freaky-ass dance parties. Photos of what seems like every goddamn thing that happened during those 75 years. It's like spying on someone through the window, or going through the trash for secrets. Totally square, totally amazing.
