Cache in Mexico, easy to get to from El Paso?

[+illegible]

My family and I are going to be driving from Silver City, NM to El Paso, TX, as part of a geocaching road trip. Any suggestions for how we can easily get a cache in Mexico, to add another country to our list? We have US passports, but we have a rental car so we'll have to park it on the US side and walk into Mexico. I'm looking at the caches in Juarez and I'm not optimistic that we'll be able to actually find them -- a lot of DNFs -- but maybe there's something I'm missing.
