I buy soda on a biweekly to triweekly rate as I consume roughly 1 bottle of diet drink every 1.25 days.  I don’t bring all the bottles in at once and leave the rest in my car.  In the Cherokee this was fine as I could easily stand them upright and they’d be fine as I gradually brought them in, but with the open bed of the GMC Sierra that’s become a bit more of a nuisance:
Frank:  Take the God-damn soda out of the GMC.
Me:  Why?
Frank: I borrowed the Sierra to pick up a replacement fender and every time I made a stop is sounded like a half-dozen ‘tards are rollerblades attacked to the bumper were slamming their heads into the tail-gate.
That’s exactly what I thought of that noise too……
