3 dally classes, thats at Ryton on dunsmore very popular venue and good roads up to there, I used to go to Wood Green Animal shelter a lot for Opens thats just up the A1, there are some more on the Fosse data website you could always go in AVNSC Utility if you dont want to travel for breed classes there's one in Ipswich that has that but you need to enter by this Friday (you can do it online).
Hope that helps. I have between an hour and a half and four hours travelling to get to Opens and the roads over here are'nt great
