That looks very pretty. I would love to spend time exploring the abandoned structures, dangerous or no! Is it possible / safe-ish to camp in the mountains? Night photography with ruins are just plain cool :-)
I totally fee you with the "old bike," too! When I lived in Spain, I always bought a bike, but it was always a cheap one. Climbing mountains with a heavy frame and gears that don't work quite right can be a heck of a challenge. It's a good work out, though!
Yeah its hard to find good abandoned places but when you do its worth it. Those mountains wreck your legs.
