Planning an Interstate Excursion: Nevada

We have scouted (via internet) for sites that could resemble the desert border crossing to California. In order to film these false border scenes, we will travel three hours to Nevada, where desert is plentiful. Our lead actor, Diego, can drive and is willing to drive there too, so we're going this weekend before it gets any colder. The temperature was 24 degrees this morning, but by afternoon it gets above 60 degrees. Diego is supposed to be crossing the hot Sonoran Desert in in a t-shirt--hope nobody catches pneumonia. We'll shoot extra footage, including extra scenery in case we need to do some compositing work in post production editing.
