I will happily admit that I am Wrong-Way Corrigan. If there are two possible directions, I’ll take the wrong one. If there are three, I’ll take both wrong ones before taking the right one. However, it wouldn’t take me more than an hour to figure out I was going in the wrong direction just by the road signs. They do have road signs in Croatia, don’t they?!
But forget road signs !
Unless driving some kinda vehicle with saddle tanks, the second petrol stop shoulda been at least a partial clue !
