I'd never knowingly been to any prehistoric site before I was given a copy of TMA. I devoured the essays at the front, and read the gazetteer with some interest. As luck would have it, a couple of months later, I was lucky enough to go on a camping holiday in Cornwall.
I went to quite a few sites there. I think the first was Men-an-tol.
I'd love to go back there some time. The tip of Cornwall is so beautiful.
