Every weekend - Sports Book.
Don't let the numbers and the hype fool you. 99% of the victims are involved or related to it one way or the other and that includes the 2 American Citizens - the consulate employee and prison worker - that they made a big deal out of on the news a little bit ago.
Knowing you won't know what I'm talking about but my area is El Centro. The Pronaf area has a good amount of problems and that's a few miles east of it. Further east and basically out of town is an area called "The Valley of Juarez" - that and the maquila area are where the most problems are. Most places in El Centro pay the protection and have no problems.
More recently, it all gives the common street punks an opportunity to blend in with the rest of the stats and violence. That and the fact that they tore down most of the good, old nite clubs over the last 3 years has me out of there before the sun goes down nowadays. No more bus rides across town, no more dinner engagements - no more 2 or 3 day stay-overs either.
No matter as my "reasons" have, for the most part, moved back to their family and homes further south. Except for one - she just disappeared. Her brother had some involvements so who knows what happened to them. In the fall of '06, she had told me to expect the crap to hit the fan in Juarez after the New Year and she was spot on.
For someone like me, the biggest problem has always been and will always be the Policia. Once the sun goes down, a gringo is a walking target for those corrupt pieces of $#!& nowadays.
