BITD I toured Andalucia for 7 weeks. Grades can get ugly with no notice. One day I wanted to go into the center of a town for snacks or something. There was a warning sign informing people that the grade hit 14%. Spent a couple of nights on the coast below Mojacar. Took a day ride into town with the gear back at camp. Even with a 22x34 low gear I had to walk a bit. I think they built a lot of small towns up on steep hills so they could throw hot oil down on invaders.
