I got into it in early '87 I think when I was about 14. I went to Cycle Logical in London, and saw the Muddy Foxes there, was blown away with how damned purposeful the things looked.
Shortly after a friend got a Raleigh Maverick 15, a few goes on that and I knew I had to have one. A few months later, I had a bad crash on my road bike, the council admitted liability and paid up, two weeks later and £400 lighter I walked out of the local Raleigh dealer with my Ozark.
Having been a cub and a scout I'd always been into getting up on the downs, but for hikes and things, on foot. Being up there on a bike was amazing - the distances you could cover in a day, unbelievable! The look of disbelief on walker's faces was amazing too, seeing someone on a bike, riding up a 20% muddy track, great stuff...
