we will be on a road trip in early August. On our way to Grand Canyon, we are going to spend a night in Palm Springs. We have planned to see a bit of Joshua Tree NP (just driving through it) on our way to Laughlin. We won´t be able to leave Palm Springs very early that day, maybe at about 9:30. I know it will be incredibly hot and I am a bit concerned... we don´t want to end with a broken car and no chance to use the cell phone.
Should we skip the drive through Joshua Tree altogether?
And what would be the best route to Laughlin? The shortest route seems to be via Amboy Road, but probably not the safest. Would it be fine to drive 62 and 95?
