Fingers - Do not fear, I am for real.
I did ask the question, so therefore I was seeking an answer. Once I get past Bristol (south) or Worcester (north) I ain't got a clue! I could have looked at Multimap or opened up a road atlas, but I thought simply asking would be sufficient. Remember, we all have strengths and weaknesses, and travelling happens to be the latter for me. I'm sure I make up for this ignorance elsewhere!
Anyhoo - Dudley it is then. Don't worry, I won't get lost!
