One of my first rides in Japan, I was on a small highway and suddenly there was a fork in the road. Sign pointing left was something like... "Turtle Hill" and right was something so local I couldn't read it. Nothing at all like "This way to Kyoto" or "That way to Tokyo". Both were clover-leafs that lead to tollways. Totally nothin' nowhere places that only rice-farmer Jo ever heard of. There was no shoulder, so I quickly pulled over between the line and the Jersey barrier, and yanked out my brand new cell phone (the old, pre-flip type).
"Honey. I'm on the freeway..."
"Did you crash!?!"
"No, but there's something about Turtle Hill... and some... village. Which way do I go?"
"How should I know?"
"But...you're from here!"
"I'm from the city. We use trains. How would I know about Japanese highways?"

I took a right. It worked out.
