Great time indeed. A membership costs $25 and that gets you one race with it. I got 19 laps in on that one race. The course is about 1/4 mile long. After the membership you get races for a cheaper cost. A 40 lap race is $20. You will be feeling it after that race. The track is exceptionally smooth and the course is fun. You have to be somewhat smooth and agressive driving as if you lose momentum people will catch you rather quickly. I don't know about that ask my brother who I put 3/4 of lap lead on.
You can bring your own helmet and neck collar so you don't have to wear the public helmet.
Who knows who wore that thing, remember you are in Delaware! They do have a website I think.
