I thoroughly enjoyed the night races I've done, all of them in Michigan. At that time they only had two light/generator trailers and one was at the finish so there was literally only one other light on the course. The rest of the course was basically pitch black - there weren't even street lights. There were some bleed through lighting from the opposite side of the course as well as the sporadic store sign or something that wasn't turned off, but it was a small town so no big stores or lit up parking lots. Not something I'd be keen on doing now but back in the day it was incredible.
