Years ago while stationed at Matagorda Island, Reynosa Mexico was our playground (across from McAllen, TX). It was a nice quite Mexican city with good bars and good restaurants. Today it is one of the murder capitals along the border. The dollar value of cocaine has the dealers fighting each other as well as the police for control. A lot has been written about the number of guns going from America to Mexico, but the quantity and types of guns points to a source other than American gun show.
I use to visit Mexico occasionally, had some great fishing and hunting experiences down there, but I can live without it today. Matter of fact, I would encourage everyone who lives near the border to arm themselves, you may see the day, and soon, that you have to protect yourself and family from the dealers.
