My cousin lives just across the border in Piedras Negras, she's married to a Mexican national. She's alway inviting us to come visit their ranch saying, she feels safer there than here. We're not quite ready to visit just yet.
It's kinda the luck of the draw. I've been to Mexico many times and have never experienced any problem personally. My latest visit was Cancun.
When we arrived home, we found an article reporting 8 execution style murders in Cancun city very close to where we were staying.
