     We all remember seeing hitchhikers, standing by the side of the road, thumb sticking out, waiting for a

lift. But it is getting rare nowadays. What killed hitchhiking? Safety is often mentioned as a reason. Movies

about murderous hitchhikers and real-life crime have put many drivers off picking up hitchhikers. That no

single women picked me up on my journey to Manchester no doubt reflects the safety fear: a large, strangely

dressed man is seen as dangerous.

     But the reason may be more complex: hitchhiking happens where people don't have cars and transport

services are poor. Plenty of people still hitchhike in Poland and Romania. Perhaps the rising level of car

ownership in the UK means the few people left hitchhiking are usually considered strange. Why can't they

afford cars? Why can't they take the coach or the train?

     Three-quarters of the UK population have access to a car; many of the remainder will be quite old. The

potential hitchhiking population is therefore small. Yet my trip proves it's still possible to hitchhike. The

people who picked me up were very interesting-lawyer, retired surgeon, tank commander, carpenter, man

who lived in an isolated farmhouse and a couple living up in the mountains. My conclusion is that only really

interesting people are mad enough to pick up fat blokes in red, spotted scarves. Most just wanted to do

someone a good turn; a few said they were so surprised to see a hitchhiker that they couldn't help stopping.

     The future of hitchhiking most likely lies with car-sharing organised over the Internet, via sites such as

hitchhikers, org. But for now, you can still stick your thumb out (actually, I didn't do much of that, preferring

just to hold up my destination sign) and people-wonderful, caring, sharing, unafraid people-will stop.

     In the UK, with its cheap coaches and reasonable rail service, I don't think I'll make a habit of it. But having

enjoyed it so much, I'm ready now to do a big trip across Europe and beyond. In the 1970s a female friend of

my wife's hitchhiked to India. How wonderful it would be to have another go, though Afghanistan might be a

challenge. I wish I'd got that tank commander's mobile number.
