Here are some dates I found on various circuit web sites,
Jan 30th Croft
Feb 13th Blyton
Mar 6th Croft
Mar 12th Lydden
May 29th K'Hill
Jul 24th Pembrey
Sep 24th K'Hill
I think we can presume that Lydden will have the Easter & August bank holidays again.
The strange thing is the Croft, Knockhill & Pembrey calanders have no mention of the RSS
