    Portaledges – Hanging Tents Rock climbers began to stay overnight on the rocks in the 50’s. At first they were searching for convenient mountain “shelves” to replace a bed, and now they are using hanging tent systems called portaledges. They are designed specially for rock climbers who have to spend multiple days and nights on a big wall climb. Honestly, I wouldn’t be able to sleep hundreds or thousands feet off the ground! Maybe you wouldn’t be scared. Take a look.                      http://fillinn.com/portaledges-hanging-tents/    |
