I don't know where you are in Sufolk but there is a club in Great Yarmouth of which i'm a member and one based aound the Southwold area but I can't remember the name of that one. There are some around ipswich way i'm sure and also Norwich have a club. Most clubs make sure you are accompanied for several marsh vivsits until thay are sure you are competant and safe for your own good. If they let you out on your own straight away then there probably not worth joining. Let me know where you are and I will try and help get you intouch with your local club.
