I'm traveling around South America for a couple of months, and every day is filled with stuff I never would have imagined otherwise. (Btw, my Spanish isn't very good yet, but estoy aprendiendo. Deal with it.) I'll try to share a few glimpses of what I find here.
You know you've arrived in Bogota when the airport is filled with signs warning you not to mule.

Interesting that the deterrent here isn't jail, violent reprisal, or any other punishment -- they're appealing to shame and family honor.
Here's another anti-mule sign, this one posted in front of the McDonald's in the airport food court.

Again, the emphasis is on family shame above all other deterrents. Including the nice young men with with large weapons nearby.
Not sure what that says about Colombian culture, but it's hard to imagine the U.S. analog having any effect: Kids! If you got involved with drugs -- your parents wouldn't like it.
Yeah. That would totally work.
Not sure how well it's working in Colombia, either. Still fascinating to see.
