We finally found a roadside store along the Southern Arizona highway, and it was huge.
Inside they had all kinds of stuff for sale – postcards, gum, travel toothbrushes, beef jerky, deodorant, wind chimes, ceramic cow skulls, dolls with fairy wings, silver and turquoise Native American jewelry, rolling suitcases, and Michael Jackson frog figurines.
Everything except tampons.
Which is actually all I had needed.
