Just FYI, the way that CD5 ended up being laid out wasn't as originally planned, due to the rain. The main camping area was supposed to be around where Klub Kevlar was. Also the Dirt Track area was supposed to be for day trippers' parking and overflow camping only. Also, the large area below and between the canteen and the track was supposed to be used for the trade display/pits, but that couldn't happen either.
Also on the dirt track issue, one fact remains: it's a "nice to have" feature of CD, but it just costs too much to be a viable option.
At CD4 we went to the trouble of having the Dirt Track available for riding (especially after the outcry on this Forum), and despite the rain putting a damper on things then too, the reality was that only 12 dirt track bikes actually turned up to the event. This just does not justify the extra track hire, additional MA permit fee/ rider levies, more flaggies and additional Paramedic crew that we have to have, to make it possible to run the Dirt Track.
At the end of the day, there are several great Vintage Dirt Track meetings held each year, and they need the support of the Vintage community, rather than have Dirt Track at CD.
