4 wheeling in death valley

Last week I went 4 wheeling in the death valley, with Pascale & KB, my friends from France. Early november is the right time to do that. The forecast is usually nice. The temperature is not too hot, (around 80–90ºF). The only problem is that the night comes very early. It’s dark at 5pm. |
