The last time I was in Mexico, over 15 years ago, there were federales at every corner with automatic weapons. This time, the only police officer I saw was directing traffic. I felt totally safe, although swamped by people trying to sell us everything from candy to wooden flowers to manicures/pedicures to dental work.
I managed to find a knock off Michael Kors cross-body purse for $20. It looks great and it's the perfect size. Other than that, I restrained. We don't need pottery.
I took a few pictures of the wall as well and on our way back home we watched a truck go through the border control with a payload higher than the stand he was going across.
