This was a very unfortunate and probably isolated incident in the outskirts of Puerto Vallarta. Good thing is nobody was hurt.
We all know crime is worldwide and often drugsrelated.
We are in PVR for (again) a long winterstay, with us thousands of americans, canadians and I know all of them are enjoying this stay. Restaurants are doing good business, people walk on the Malecon at night without any problem or doubting their safety.
This robbery has taken place this time in Mexico, but you might remember similar incidents in the USA in the past:
