Not that close but there is/was a branch that meets at a pub in Stanway just outside Colchester (on your side at least). I rolled over there on my GF Bitza about a year ago. Some 30 blokes standing around drinking and just a handful of bikes. Now I'm a fairly gregarious type but these folks wouldn't give me the time of day - miserable Bs. I did get chatting with a couple of older gents who were a little more accommodating, and moaning gently about lack of new members and not really getting out and about much. I'm not surprised, I've never been back.
I'm Braintree based BTW.
