Agua Fria National Monument - a (public) land toilets forgot

I've had my heart set on camping in Agua Fria for a while. A popular site told me there were toilets, and I like toilets, so I went to see them.

This is NOT a toilet.

It was fine.

I got discouraged by the no-toilets at either exit (259 or 256, Route 17). The day was cloudy, my mood was cloudy, the river was cloudy.

I SOSed on Facebook, and got several ideas for overnighting. I chose Sunset Point Rest Area. I know, but let me tell you about it. It's not skeevy. It's pretty busy, so it's not scary, but somehow it's quiet. Maybe because it's off the highway. Anyway, I put up my blackout curtains, put on my hat, and snuggled down happily for the night. There are signs indicating overnight parking is permitted, and other signs encouraging you to rest until you're rested.

Once you're that rested, go to Rock Springs for pie. 

The next day I met my cousin at her hotel. Yay Cousin! She had to go do work stuff, which left me to do hotel stuff on her behalf. That gave me time to figure out stuff. To create a plan. To take over the world.

Go, little tree! We're ROOTING for you! No one LEAVES without an orange. 

I'm camping in a spot not mentioned on the above popular site, and I'll change that later. Lots of you know about it already. It's quiet, except for occasional low-flying jets, whatever. It also has toilets. It's west of Phoenix. 

Brainstorm with me: I want a solar solution to charging my Mac (which uses a weirdo charge connection, the SmartMag). My two solar panels each have a 12v adapter, but neither panel produces enough oomph to charge my computer, and I can't link the two. I'm thinking I need about a 60 watt panel to charge it - does that sound right?

On the other hand, my Poweradd solar charger/battery pack might have what it takes to give it a boost, but I'd need a super-weird USB-to-12v adapter, or an even weirder super-weird USB-to-Magsafe adapter.

Any ideas?

Otherwise, I'm hooked up pretty well. I'm surfing along comfortably with my Millenicom Jetpack and my Wilson Sleek 4G-V, being powered by my Goal Zero solar panel (a Woot impulse purchase).
