I'm posting a link this week. No, this isn't anywhere I've been - I'm much too cowardly to venture into such a terrifying place as this - but it's fascinating to think that people voluntarily go up there, presumably for the thrill of danger.
Here it is. While you're watching, you might like to reflect on a few things.
According to Wiki, Camino Del Rey was built between 1901 and 1905 to carry materials up to the hydroelectric plants in the Spanish mountains. It is a concrete walkway, a metre wide, supported by steel girders. Just imagine what it must have taken to build such a precarious path in so inhospitable a location. Were lives lost?
It just goes to show the determination - some might even say foolhardiness - of the human spirit. But if people can imagine something, and they need it badly enough, they will succeed. It's inspiring.
