I've been on the Inet for 20 years. I've been through many forums and the repeats are all part of the deal. The newbies can't be expected to read all the posts, so repeats are the norm. It's the ones that have the patients to deal with it. That make it a good or ... forum.
Back to the topic, I also live in Monterrey and remember how peaceful it was just two years ago. I also remember the first Shoot Out near our area and how we blew it off...LOL! Now it's bombs and sireins even helicopters on a nightly basis, even seen a few hanging off the overpasses dead by their ankles. I wouldn't take anything lightly in Mexico anywhere....
