It's hot outside, really hot.
One hundred plus degrees hot, and you're driving a fifteen year old car.
New air conditioning system, trying to make it up the hill at seventy-five.
The needle edges towards the "H".
When in doubt:
Go slower.
Turn off the airconditioning.
Get off the freeway.
Turn off the car.
CALL DAD!
Oh, PS:
Turn on the heater!
