Sorry - that was directed at queerpunk, I clearly have not mastered the mobile interface for the forum.
Re: DLV, based on a quick estimate, it looks like ~170 racers earned points in 2015. Is that pretty much the population of regular track users? Do you see a sizable population of consistent riders who don't race?
Makes me wonder if people don't generally ride the track if they don't race on it. Which wouldn't be terribly surprising if true.
