I plan on doing some travelling eiter europe or america this year, and was just curious on whether or not you bombers would do this in order to move around obviously the dangers are obvious but have you or would you ever do so!!
Ya hitch-hiking isn't reliable. I've never seen a hiker get picked up or even had the thought cross my mind of picking one up no matter what they look like. Though I have heard some stories from people I know that have hitch-hiked quite a distance.
Also, I live in Canada. It's illegal here, and I would also say safer.
Middle and Southern Sweden is quite hitch-hiking-friendly, in my experience. I've only tried it in Sweden, Britain and the Netherlands, but I have only good experiences (as far as I can remember).
I wouldn't mind resorting to it for a longer trip, but like others have said, might not be best as your only option, regardless of people's fears, it will probably be extremely time-consuming...
...But also: Fun!
