Road Map

I have no sense of direction so imagine my delight when I found this rock on the beach. Can you believe it? A map of San Francisco! I labeled the streets to prove it. Of course I always carry a phone in my pocket, and I ask Siri for directions every few minutes. But sometimes when I over-ask, the charge runs out on my phone. Next time that happens, no problemo, because I've started carrying this rock in my other pocket.
