We found this short clip of people frolicking at the Sutro Baths -- which, really, looks like so much fun! -- shot by Thomas Edison on October 25, 1897. But our question is this: how did they get their towels to dry? Sutro Baths must have supplied them, right? Unless of course you had to bring your own. But we lived out in that perma-fog part of SF, and our towels never dried unless we put them in a dryer for well over an hour.
