You are looking south at the border crossing from California to Algodones, Baja California, Mexico.
Algodones is a short distance from Yuma, Arizona, which makes this Mexican border town a big shopping destination for the army of retired people who populate the area.
There are countless pharmacies in Algodones, with pharmacy hawkers trying to direct you inside. I remember a memorable visit, with my mom and dad, when a pharmacy hawker said to me, "You sir, you look like you could use the Viagra, bargain prices."
Most of the streets are not paved in Algodones. You explore a big labyrinth of shops, like a maze, finding all sorts of good stuff. And things to eat. My mom and dad had a favorite bakery, where they'd go for donuts and coffee after getting dental work or a haircut in Algodones. My mom and dad being so free-spirited surprised me.
I've not crossed the border into Mexico at Algodones since 2000. I do not know if passports are now required, like is now mandatory to cross into Canada. I hope it is still easy to walk across the border to Algodones.
