hi bdshim,
I am from Suffolk too (if you hadn't guessed from the name), in fact I work just outside of Ipswich. There isn't a Suffolk meet up at present but the Cambridgeshire and Norfolk ones aren't too far away.
I look at Rendlesham forest on Google maps but I am not sure about the permissions there and I haven't had a chance to go there. I know some people visit Thetford forest but again permissions will be hard to achieve.
I would think about what you want to practice and then think about where could be suitable, surprisingly large amounts of stuff can practised without necessarily being out. Sorry I haven't been too much help.
Steve
