Tough work in San Francisco

The Hercules (1908- 1925) was an outside tug, built to live and pull in the open ocean. She could steam for 30 days or 8000 miles without refueling. Between 1908 and 1924 Hercules towed sailing ships, schooners, disabled steamers and hard equipments to distant ports like Papete, Tahiti and Jacksonville Florida. While watching her finally enjoying a long holidays in the Sfo harbour, I think I'm a kind of Hercules carrying 12kg of sweet Italo Australian baby on my shoulders up and down for Sfo hills. I can keep walking for 4-5 h without food but now is time for a stop. Fisherman wharf, lunch at the Crab Station. Fried calamari and clam chowder in bread for 15usd. Smoky China atmosphere like in a maritime Blade Runner scenario. Then back to the cable cars for a new ride.
Cable cars are not electric, they move up and down because are hooked to a big iron wire that passes under San Francisco main roads. The grip is like a giant pair of pliers that clamps onto the moving cable. When the grip has hold of the cable,  the car is pulled along with it. Operating the grip require a degree of practice and a tremendous amount of strength. This is the gripman job. Tough works in San Francisco. So while I'm assisting Charlie changing a poopy napy in the cable car museum in front of the portraits of Andrew Hallidie, the inventor of the cable cars, just in 1 minute with a perfect organization, I realize her level of training has a lot to share with the gripmans.
