Oulton has been around £150 for as long as I have been doing trackdays (peak time), some organisers are starting to bump the price up a couple of quid now, and someone like Track-time are charging more if you turn up on the day
Surely they'd be glad to sell the place let alone at a premium
Luckily No Limits will give DSC members a discount, plus several other forums have some affliliation with other TD comapnies (Throttle Monkey to name but one)
Although I do find the prices of say a Brands day shocking by comparison, but Apex's deal was far to good to miss out on at that price making it a must do for me at least.
Hopefully a similar day (unofficial DSC Track day) is going to happen next year at Oulton or Donnington, possibly Croft, I have already approached one company regarding this and hopefully have something on the table as soon as 2006 dates come out.
Dibble anytime you want to venture further North for a track day you're more than welcome mate
