Nice points raised Standard Noise but I was being flippant when I mentioned cows. The real pain in my view is still trying to negotiate the one way system leaving Bristol on the A38 for the airport. It's confusing and frustrating when you miss the turn because you're stuck in the wrong lane. None of it is even dual carriageway which makes it a really slow drive out there. There is no other means of getting there either.
Of course if you live the other side of the airport then driving there is not too bad. But now Plymouth has gone it only really leaves Exeter and Lulsgate to serve that part of England.
