'When you join the Ramblers you are normally allocated to your nearest group based on your postcode, unless you request otherwise from the central office Membership Department. Whichever Group you join, you may additionally join the activities of any other Rambler's Group in the country. Members of the public may take part as guests with a view to becoming a member of the Ramblers. It is customary to attend no more than three activities before deciding whether or not to join.'
