Bruce,
It would be great if we could use our own classes but every track seems to structure nostalgia races differently, with their own classes, so we have to play the game their way. But there's no reason we couldn't arrange some informal Inliner class runoffs, at least during heads-up qualifying. At Denver there was a Flathead/Inline class but I'm not sure how they paired up the competitors. This is a well-established event held by the Denver Flathead club, and the Bandimere Speedway owners were very supportive of the older stuff. Most tracks don't want to bother; there's no money in it for them. I've been forewarned not to expect any special accomodations at Sacramento.
