Went on a flydrive to California with 3 mates in about 1985/6.
I was 19/20, so had dodgy id, so I could get a pint.
Anyway, we were driving from San Francisco to Las Vegas through that area in this big air conditioned Ford sedan, windows up, music playing, all cool and comfortable.
We stop for petrol and a toilet break at this one horse town.
We opened the doors and feck me, nearly fainted. The heat blast was shocking.
Laughing, we went into the shop and bought drinks and ice creams.
I kid you not, the ice creams had melted on our hands before we got back to the car!
