Boy, that's some conclusive evidence there. If he hasn't made him self public, he must be dead. I'll wait for something a little more concrete before I make up my mind.
Perhaps you should wait for something a little more "granite" than that. LOL
Keep in mind that when our DOD and Military folks talk about "severe terrain" and "high altitude" that's almost techno speak. These caves can be at altitudes higher than a helo can fly and incline and roughness can be such that motorized vehicles can't get there.
So if a huge "bunker buster" blasted a cave complex to pea gravel, it will never become "concrete." I.E. UBL will never be found.
Oh! Yes, I have been there. I traveled from Peshawar to Kabul through the Kyber Pass on a train called the Kyber Mail some years ago.
