Used to hitch around Europe as a teenager, from the age of sixteen I spent every summer bumming round the German speaking parts of Europe, staying with an ever-growing list of folk I'd met over there on voluntary work placements and so on. Between A levels and Uni I spent eight weeks over there, didn't have to pay once for a bed for the night, and spent the princely sum of £130 in total, mostly on food beer and fags. I met some incredibly generous people, did a lot of DIY, gardening and farm work to repay favours, could speak German so well that people refused to believe was English. I only ever felt threatened once, by a fat bloke in a big car who wanted to discuss corporal punishment in English schools in a little too much detail.
My record lift was from Pisa to Coventry in one go.
