That Dairy Queen lot sounds cool but I gotta disagree on it being worth a stop. Half the fun of these old spots is that nobody's turned them into a photo op yet. Once a place gets posted about, you get ten cars parked there on a Saturday and the vibe is gone. There was an old drive-in theater screen out near Kingston I used to pass every week, just a blank white wall in a field with weeds up to the bumper. Told myself I'd stop sometime. Next thing I know it's a solar panel farm and the screen is in pieces. So yeah, grab the pic, but maybe don't tell the whole internet where it is.

That Hilfiger kid photo is a legit time capsule. Mystery rolls are a gamble but they can pay off. The main thing is the film itself, old Tri-X that sat in a hot garage for years gets fogged and the latent images can fade. I've shot maybe a dozen found rolls and only lost two to bad storage. My move is to develop in Rodinal stand for an hour, one hour, no agitation after the first minute, because it handles the age fog better than a standard recipe. And always tell the lab if you send it out, some will straight up refuse or charge you extra for old film.
