Here's a video of an HBC Nashville Speedway ride. Its not of much interest to me during the longer days, but it was quite nice for riding at night this past winter. I still think we (MBC) should take a shot at renting out the Superspeedway in Lebanon this winter -- a bit closer to the Boro and probably a smoother track.
I have gone a couple of times, yeah the track is a little rough in a few places. But it is a great chance to do a lot of paceline work without having to worry about fido, cars, rednecks in trucks ect.
They've got my back, I was in a Velobella jersey (small(er)rider following the granfondo wheel). The track is great: controlled environment, some fun races for willing to participate, many people to socialize. I love it.
