T-Max and the Autocord II, Roll 10 (#4)

First time (knowingly) using T-Max 100 in the Autocord II. I definitely underestimated the light levels for most of this roll. Might have to break down and get a light meter. I have NO idea what this is. None. Must have taken it at night of cars in the street, but other than that, I got nothing. Home-processed black and white roll #17 (Developer: Rodinal).
