The highlight of my day:
An excellent dinosaur in Benson, AZ (we think). See how from this angle he looks a little bit like a pelican?

So, really it should take about three seconds to drive from Tucson to Nogales, since they make freeways pretty damn straight out here in the desert and set the speed limit at 75. But we decided to take "unimproved forest roads" along the border. We thought this would be very interesting and cultural and whatever.* Let me just tell you, it pretty much rattled Mouse's teeth out. Here's the sign at the beginning of the route:
And then they looked around and upgraded us from "dirt" to "bump bump bump, ow."
Mouse wished for her sports bra today, friends. But at the end, there was a chimichanga with green chile, so hurray. Also, we did some excellent doohicky shopping on the other side of the border in Nogales, and I'll share photos of that tomorrow. (THERE ARE BOOTS.)

Okay, Mouse is loopy and is sending herself to bed. Ta ta.

*From there, the border really just looks like a fence.
