Cable cars aren't a cheap ride. No transfers. No exchanges. $3.00 flat fee will get you from one end of the line to another, but you may find yourself crammed into the middle, like me. It's more fun to ride hanging off the sides. Still, I love riding them when I visit San Francisco. Something about the noise of the cable, the smell of the wood brakes, the clang-clang of the bell and watching the car operators really put some forces into getting those cars moving...
