Park in the Quechan Tribe parking lot on the U.S side of the border ($5).

Walk across the border into Mexico.

Turn right at the first intersection, (Avenida A).

Go one block  (just say "no gracias" to the street vendors).

Turn right on Tercera,  (you'll see Yuma Cafe to your left across the street)

Turn left into Internacional Way (at the barbershop).

We are the green building in the middle of the block.
