I had one of these, the day before yesterday.
I was driving north up to Encinitas, on the I-5, with the sun-roof shade open and the Beach Boys belting out 'Sloop John B' on the MP3 player. Turned it up loud. The Pacific Ocean was over on the left, the fabulous freeway unrolled ahead, and I was flying past some of the world's most beautiful trucks - immaculate chrome shining like silver, great flashes of scarlet paint.
Even in the day's May Grey, when the sea is steely and the horizon's blurry and the sky feels like it's only just hanging in there, just overhead, I thought there wasn't a single place in the world where I'd rather be.
It was perfect!
