Hello Richard
I was ever so interested to hear about your gravity-defying exploits above White Sheet Hill. There was certainly enough draught up there when I visited. I was slightly concerned I was going to take off myself. It must have given you a very different impression of the place to see it mapped out below you.
It sounds a bit sad, but I have to say this website is a pretty good place to start picking up stuff about our country's prehistoric remains. There are quite of lot of people with pretty specific interests and they know a lot about their subject!
I'm sure people will be happy to rattle off a list of books. I like Ronald Hutton's book about the pagan religions of the british isles. Of course you must get your hands on Julian Cope's book! I don't know what people will suggest specifically about Iron Age forts..
Welcome to the fold anyway. You live in the same area of the country as I do so I will look forward to your contributions!
