Before Dino came over Sunday morning to install the A/C condenser, I needed help from a few able bodied men to hoist the condenser up to the roof. Nathan and Angel were up to the task after some ribs from Fat Willy's (awesome!) and a beer.
I tied a cargo net from a single rope, then looped a 2nd rope through the rings to carry the condenser. Nathan and Angel were up top pulling the condenser up, and I was pushing from the bottom on a ladder. It was far too dangerous of a situation, but it went quickly.
This guy taught me how to tie the cargo net, found it on you-tubular (blatant 80's reference for fellow gen-Xers).
