What's wrong with hitching? I used to hitch the length and breadth of the country (even to an interview once!) into my thirties. Great way to travel & to meet profoundly weird people. You've got guaranteed booze through the evening, a place in the dog basket overnight and a hearty breakfast the following morning. Money is no excuse, as Jon has already proven.
do you see the offers here? free booze, bed, breakfast and even a train ticket, you really have no excuse not to go
and Steve is right, hitching works when money is short, I did Rome to Cornwall in about a day and a half once (helped massivly by an all night lift where the guy didn't mind me sleeping)
