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.
