We have booked flights to Clifornia for 2 week flydrive in August-are very tempted to have 2 nights in death valley then a night or two in Las Vegas...however temperatures look unbelievable for death valley-up to 55C!! Has anyone been and will we literally fry? DCs age 9 and 11-they cope well at around 35-40 degrees in the sun in Italy, Spain etc but not wure if this would be foolhardy!!
