Laredo isnt as bad as it used to be, just make sure you have money to eat and such for a couple days if needed, I wont sit anywhere longer then that. If it costs me 150 bucks to get out then so be it. Its better to bite the bullet and move then sit past two days unless a Great load is waiting, Ive run from Laredo to Michigan both times Ive been there and thats a pretty good paycheck.
Ten years ago when I first went to Laredo it was a crappy dirty bad roads, bad food, bad places to load into and out of, Now they have two very nice clean truckstops to stay at, eat at or overnite at with all facilities. TWO THINGS Never go to Laredo with anything Illegal in your vehicle as the dogs there will sniff it out, and keep an eye on your vehicle if its sitting outside secure parking, do your own roadside check and be sure no one has added anything to your truck because it happens...
Laredo has a Boys town which you prolly want to stay out of, stay on the USA side and if you have to go down south let someone know when your due back, where your going, and be sure your LEGAL...ITS JUST ANOTHER port CITY AND IT HAS ALL THE CRAZINESS, including Drug Smuggling, Police and Border patrol everywhere and on your way out of town you will be inspected and detected at the Highway Inspection station that ALL traffic passes thru. Mind your Ps and Qs and youll have no issues.
