I once hitched home to the Midlands from Somerset and the first person I stopped actually went within 5 miles of my house which was unbelieveable - I got home quicker than I ever had done before! I never had a problem hitching, I met some interesting folks, and I also have picked up a fair few myself too
One tip - I used to deliberately trap the seatbelt in the door as I shut it getting in, that way I learned how to open it up again if I needed to get out again sharpish
Oh and I once picked up a couple going home from Glastonbury - not a good idea after a week or more without a shower
