Friend of mine was crossing Texican territory and noticed a curious road sign. It looked legit by quality of it's construction, but it said something strange. Apparently the sign was there to remind people that slavery and human trafficking is against the law.
The friend thought it was a local joke. But traveling further trough the vast Texican country, he noticed more of those signs.
Now, the friend failed to take a picture or to write down the exact words of the signs (so I could google it), ergo I hereby call upon the Foo Texican Emissaries to help me understand this mystery.
