We have a fire station near us that houses one of those dual-steered ladder trucks. Apparently the various fire crews alternate the task of grocery shopping for the station. In order to be able to respond rapidly to a call, they take their vehicle to the nearby shopping mall grocery. More than once I've turned up a lane in the parking lot only to have one of those monsters coming down the opposite way. It's a daunting experience* but the guys who handle those things are real professionals and can thread needles with their battleship-sized grocery truck. My hat is off to them.

* Perhaps my most daunting driving experience happened in Switzerland. The Swiss are passionately neutral but wisely maintain a modern military. I had just turned on to a small country road and was stunned to look in the rear view mirror and stare down the barrel of the huge (to me) cannon on a tank! It was following me, surprisingly quietly due to rubber tread pads. Not wanting to risk a road rage incident with an armed vehicle, I pulled over at the first opportunity and let it pass.
