Then we made a run for the border. Even though I forgot to bring my birth certificate, we talked to some locals here and heard that you can park on the US side and walk over to Nogales, Mexico, and all you need to get back in is a driver's license. So we hit I-19 and went about 40 miles south to the border.
On the way back, we stopped at a pretty famous little spice shop, the Santa Cruz Chili & Spice Co, in Tumacacori. Then we continued north through a little "city" called Tubac. It's called an "artist colony" down here but it's basically a bunch of hippies selling arts and crafts stuff. But it was good enough for us to look around and grab a quick bite to tide us over until dinner.
We spent the next few hours beating up the rental car driving through Madera Canyon and Box Canyon where we witnessed a typical (i.e. awesome) Arizona sunset. Afterwards, we picked up my dad (since mom was a little under the weather) for some dinner at an awesome local Mexican place right in Green Valley called Manuel's. (Every time I come down here, I absolutely have to go to Manuel's at least once!)
Even though I was tired by this point, Denise somehow talked me into going a few miles up the road to the Desert Diamond Casino where we played some slots for a couple hours. Then it was back to the hotel for some much-needed sleep.
