I couldn't tell you - I'm still not on the BoD listserve, apparently.
I'll be at the TMS event, expecting only three runs, but I'm sure the course will be fun. I'd like to go to that LSBMWCCA twi-night event, but I don't think I'm going to make it.
Besides, having run around Hallett for a few laps in the dark, I can tell you that the OEM Miata headlights are pitifully weak for that kind of thing!
