If anyone is tempted to try hitchhiking here are a few tips (if you haven't done it before but apologies if you have). Drivers only have a few seconds to decide whether or not to pick you up (also, whether it’s possible to pick you up). Good drivers hate inconveniencing others behind them so if you’re thumbing a lift choose a spot on a straight bit of road and stand 20-30 yards before a layby, or somewhere else the driver can safely stop. It’s up to you whether you have a sign with your destination written on it (I never did) but if you do use a sign make it simple and clear with PLEASE written on it. Be careful with your bags or rucksack (I once scratched someone’s car with my rucksack frame and felt really bad about it). If you’re worried about your safety don’t get in a car with a driver (or his/her passengers) that you don’t like the look of and (this is something people of my generation didn’t have) once in ask the driver as soon as possible if you can call a friend with your mobile – it’s a clear signal that you’re in touch with the world and they know more-or-less where you are.
