Driving in the left lane of a four-lane major road in traffic and all of a sudden it goes from sparse puddles to 18 inches of water. I was in the Civic. Dropped to 1st and slowed to 20mph and soldiered through it. The water obviously was high enough to slosh over the alternator (why did they put it near the BOTTOM of the engine?) and it came up through the drain hole (irony!) in the floor pan and utterly SOAKED my seat. A truck drove by in the opposite direction and the resulting wave was large enough to come up through the shifter boot and soak the remote for my stereo. Sigh.
Guess tomorrow I get to learn how to use our industrial-strength water extractor at work. Carpets gonna be clean as heck. Ignore the not-routed sub wiring.
