There is but one golden rule - always treat people as you would like to be treated yourself. You may find the general pace of life a bit slower in Somerset, but work is every bit as hard and competitive. You may hear people say "it will be twenty years or so before you can be considered as of the village". A bit of friendly japing there I should think. In order to feel at home, see what you can offer the community and above all, be part of the community.
If you are living in a more remote area, find out where the nearest retained fire station is. The firefighters there all live in the community and respond to fire calls from their main place of work. Without their dedication, it would be practically impossible to provide fire cover for the County. They will know all about the community and have a wealth of knowledge of local subjects and events, not just fire related issues. The Fire & Rescue Service in Somerset combined with Devon in April 2007. It has its own website with details of all station locations in Devon and Somerset and lots of other information including how to get a free home fire safety check:
A lot of local communities have set up their own websites - have a look at this one to get the general idea: www.wiveliscombe.com
Try a search yourself using a local village or town name - you may well be surprised!
