Great questions!
This year's registrations have been very steady compared to previous years, although overall numbers are down by comparison. Dieselgate certainly isn't doing us any favors with regard to excitement about TDIs, so that probably has something do with it.
Historically, we get a surge in registrations in the two weeks leading up to Fest. If that happens again this year, which I fully expect it to, our numbers will be comparable to last year's Fest. The venue this year isn't nearly as spread out as Sunday River was, so the overall feeling should be busier. I think this size venue was the right choice for this year.
