Jimster,
You miss the point. Back in the 70's, if you wanted to go to Gilbralter, you had to take a ferry to Morocco, then over to the rock. It's not so much as doing the actual drive as it is the thought of revisiting your youth.
I was in the Navy in the early 70's and did not revisit till the early 90's. What a change. Franco died in 1975. After that, Spain opened up its borders in the early 80's. A lot money flowed in from Gilbralter and the whole coast line is now over built. Its not the same Spain I lived for 4 years, but hey.. that's progress. Still luv the place and am planning to go back, sooooon.
