Sounds like the University of Nebraska They put a 16 Meade LX200 atop a parking garage. Every time a car goes up or down you can imagine what the image looks like. Since it is at the SW corner it wouldn't have been very costly to put it on its own foundation but that wasn't done, I don't know why -- money I suppose. Also it is right next to the stadium which they keep brightly lit at all times even though the team has stunk of late. The whole university uses huge "pretty" globe lights that make for the worst possible lighting for pedestians, drivers and light pollution -- but they are pretty (awful that is). Population is 2.5 times more than yours as well.

I'm deep in the north woods just outside the Paul Bunyon State Forest in northern Minnesota (47N) with mag 6.5 skies though in winter sky glow lowers that some. My 10 minute background count with 18 micron pixels runs about 350 summer, 450 winter due to added skyglow. Still very low. Makes it a lot easier to go deep quickly than your location. My population density in the 36 square miles around me is about 2 square miles per person in the winter, a bit more than 1 square mile per person in the summer!

Two rather close asteroids in a month, we seem to be in a shooting gallery right now.
