Looks like Oulton then
I've spoken to Mark at No Limits and we're all set in principle. We can do the same as we've done for other 'unofficial' DSC dates with No Limits eg at Cadwell.
Oulton is a superb circuit, one of the best, but it is not allowed many dates for bike days and weekends are very rare. As soon as we get the dates for next year (which is some time away), JPM and I can agree a date and post it on the site.
From Herts, the trip to Oulton is not much different to Cadwell, sure it's further, but it's all motorway and if no hold ups, not much longer. There's no camping at Oulton, but plenty of B&B's locally.
