After only two or three hours in Laredo I was given my choice of trips and I took one to Rialto, CA which is on the eastern side of Los Angeles. The trailer was already loaded and waiting in the yard so after finding it, hooking up, doing my inspection and fueling I was out the gate and on the road again.
The fastest way from Laredo to El Paso is to take a series of state highways that run near the border with Mexico. I've run it before several times and it is really the only way I do like to leave Laredo any more. I got a few hundred miles down the road before calling it a night in Sanderson, TX. Try finding it sometime if you are bored.
