One of the boxes I cracked open was filled with old magazines and newspapers, including a few issues of the San Francisco Oracle from the late 1960's. I have no memory of where I got them. There were a couple of the old, folded tabloid style issues of Rolling Stone, too, and a stack of the Evergreen Review from the same era. The most interesting box I've opened yet. More boxes tonight, I hope, if I have the time.
Oh, I forgot to mention this informative site unearthed by elmofromok: Turns out I've been tying my shoelaces wrong all my life.
