We have driven many times from Fontana (San Bernardino County) to El Paso and all the way to Laredo, Tx. We have crossed into Juarez, Mx. as well. I do not reccomend going into Juarez, if you live in San Diego then u have probaly been to TJ, and Juarez is kind of scary, alot of trafffic, worse than Tj, infact I loved going to TJ all the time and I was actually a little scared of Juarez. I would reccomend staying in El Paso, they have alot of nice hotels and alot of nice restaurants, most of the ones you will find here in California, I know they were building a casino last time we were there. By the way look for the GIANT Roadrunner on I10 going into NM. My kids got a kick ou of it, I told them if they didn't be quiet it was going to come after us, LOL!!

Also the "THING" signs will keep you in Suspense!! Have fun, good luck and stay safe, especially at rest areas!!
