Here's a map with links to the Online Sites Guides for most of the clubs in the south of England and Wales - please do send in information on other online guides. (No link means no site.)
Please make sure that, if you want to fly any of the sites that appear in the various guides, you have any necessary membership first and make certain that the information is up to date - the best way to do this is to speak to someone personally, and they'll probably have some tips to help you get the best out of your visit too.
If you have any updated info then e-mail me (link below).
