If you make it down to southern AZ - the Tucson area - there's the Sonora Desert Museum which is the most amazing "zoo" you'll ever see, there's the Biosphere, Kitt Peak, Colossal Caves. Further south is the San Xavier del Bac Mission, the white dove of the desert. The town of Tubac is a charming little artist colony and down in Green Valley is the Titan Missile Museum. This was an actual silo and bunker that was turned into a museum. Very eerie. But important for younger folks who missed out on the Cold War.
Hey, I saw my first drug deal at age 15 in The Haight, when it was still "Haight-Ashbury" in the 1960s.
I would've never noticed it, except my dad saw a hippie palming *something* to another hippie surreptitiously and it was thrilling, lol. A real drug deal!
