Mexicans have one lane they open, that's it. Its tight. You'll want to creep through it. If you get a "red light" and get stopped, if there are two of you, one stays with the vehicle while the other gets out and opens whatever they ask. DO NOT leave anything unattended. Follow the guy where ever he/she goes. Unlike US border patrol/customs, the mexicans will usually let you follow them as they inspect. If you make it through the first guys, about 50 yards farther south, smile and waive at the military in camos , unless they step in front of your vehicle, keep driving, don't stop, don't slow down, unless they signal you. If you get stopped, again follow these guys and leave nothing unattended. If you're going to have anything come up missing, these are the guys that will do it.
All of them recently have been asking if you have guns or ammo . Make sure you don't have any cause my buddy got his truck searched. It wasn't an inspection. The camo guy "confiscated" what he said was a knife that was over 4 inches. My buddy, who spanish his pretty good, argued with him but the guy took it anyway.
As you pull away, the usual crowd, one armed guy, wheel chair guy, asking for donations. we usually stop and give them some pesos and a lollipop. Your call.
40K is the speed limit pulling away from the inspection points. We do 30k. Not kidding.
As you leave town, heading towards Rocky point. Another stop sign and Red Cross workers asking for donations. We give them some pesos or us coins ....and a lollipop . Your call.
We counted 7 cops near and around the Red Cross stop sign. Can't stress this enough.
