There are noisey days at Croft with a 105db limit, the same organisers of the quiet days usually do the noisey days as well.
The DSC two dayer is 15th and 16th June this year.
Book before 1st march and one day is £115 the two days costs £200 (if you book before Ist March) both these prices include the DSC membership that you must have.
If you can only do one day I'd recommend the 15th, its Ducatis only, so the loon count should be low, if not zero
Ducati UK bring some bikes to thrash..........er test.
I know what you mean about Ollys mount, scary Mclary, Cadwell is just as much fun, more so IMHO (having been on Ollys on closed roads many moons ago) but unlike olivers mount there is some decent space before the barriers and trees at Cadwell on corners after the really quick bits.
