I'm an enthusiastic adventurer with a rather poor memory. So I started writing down the site details from my very first days of flying in 1992. This grew into a rather ratty self-published book, but it got a great response from the flying community, and so I improved the book over a few editions to become a full colour guidebook it is today.
My other paragliding books you might be interested in are BEYOND THE INVISIBLE (1998), a metaphysical novel about freedom, and THE JOURNEY (DVD). More on the Eternity Press website.
I am also a fantasy author, where I go under the cunning alias of Greg Hamerton.
