I usually do three or four Action days at Castle Combe with track time at the Classic one. Plus RS day and Rally day. I organise the clubs attendance at the latter. Plus the Haynes Museum "Rare Breeds show" and another local motor museum summer show. So 6 or 7 usually.
Try to attend most interesting ones at our local track, Oulton Park.
We have a few good ones here in Scotland but i fancy travelling south of the border to check out the scene, a calender would be good.
