I got a response from city engineer Frank Payne by 8:30, and by the time I rode Hinkle to work at 1:00 PM, the pothole was totally filled and looks like this:
We’d like to thank city engineer Frank Payne for the quick response. We know that traffic engineering, like traffic enforcement, is a pretty thankless job that the public typically only voices complaints to. So, thanks, Denton traffic engineers.
Moral of the story: If you see something, say something. Report road hazards when you see them, Dentonites.
