Two words: Death Valley.
Okay, three words: Death Valley, August.
Wait, that's not enough. I have to add the ...
Y'see, some friends & I had decided to outfit the Valiant with two radiators. Why? Well, these things are best not asked. We just felt it would be a fun thing to do. And how better to test the performance of a quarter century old car with an extra radiator grafted on, than to drive deep into Death Valley at the height of summer?
The Good News: It got down to 95 degrees that night. On the other hand, it hit 129 that day.
The Better News: The extra radiator worked.
The Stupid Part: If it hadn't, I'd likely be dead.
The Bonus Extra Passenger: Spam Man, clearly visible on the antenna in the above photo.
