We didn't ride the cable cars.
Which isn't to say that we were boycotting the cable cars, or that there was something wrong with the cable cars. We just didn't know how to get on them.
No, really. In the movies, you see people just hop on them while they're still moving. Nobody ever buys a ticket, or pays for anything - instead you just see some guy in a leather jacket jumping on board with a churro and dragging some girl along behind him.
So that was Kyle's plan, minus the churro. But me - the little rule follower "what-if-we-get-caught-and-they-arrest-us" goody-goody wasn't on board for that. Literally. "Uh... don't we have to buy a ticket?" I asked. "Are there tickets? Surely you have to pay, right?"
Google probably would have known the answer to that. Or Siri. I'm sure it wouldn't have been that hard to figure out, had we actually tried. But instead we were like, "Well... I don't see a place to buy tickets." (While standing in the middle of the street. Not-that-near the cable cars.) "Oh well! Let's go do something else."
The truth is, I was more interested in finding The Full House house and Kyle was more interested in finding food. So we agreed to "come back to the cable cars", eventually, at some point, "before we leave".
