I have climbed radio towers in the past to work on UHF and VHF antennas. Also climbed many mountains. The most dangerous mountain was the Eiger in Switzerland. The highest was Aconcagua in the Andes in Argentina. Climbed Aconcagua by the difficult Polish Glacier route. Aconcaagua is almost 23,000 ft altitude.

Osama and Obama both have friends who bombed the Pentagon.
