If you ever find yourself near Yuma, AZ, and have a sense for "weird travel" like I do, I'd recommend taking a jaunt into Los Algodones (AKA Molar City) immediately across the border. You can park at the border station and walk in. The tiny city is pretty much entirely dedicated to discount medical sales and is packed to the brim with dentists, pharmacists, opticians, and cosmetologists. When I was there, salesmen would literally call out "cavity? cavity?" to the passersby on the street. It's like some eerie alien recreation of Las Vegas where gambling is replaced with curbside botox and root canals. We only spent about 20 minutes walking around (probably spent more time in the border office), but it was a super memorable pit stop for me.
