Portaledges
- Dr. Piton's Review of the D4 Delta2P Portaledge (By Peter Zabrok) - Peter Zabrok, aka. Dr. Piton, has slept over 800 nights on El Capitan, with 200 (or so) of them on the D4 portaledges made by John “Deucey” Middendorf. Peter gave the new Delta2P ledge a go and shares his thoughts on this unique "cantilever" design that has the short side up against the wall. Check out Piton Pete's lively review!
