So I had lunch with one of my friends who is a local law enforcement officer here. We were discussing traffic laws on bicycles...one that came up was stopping at red lights and stop signs.
Officially he said "you should probably follow the law without question"
Unofficially he said
If you ride home at 10 p.m. down ANY part of downtown and stop, don't think for a moment that the prostitutes, drug addicts and pimps won't roll you for that bike and just because they can.

We had another 2 grenade attacks within 1/4 a mile of my condo against the Mexican Navy - fun times in the RGV
