Well, I did say it was an excuse, but one of the local weathermen claims it's true. He wears a toupe so I don't entirely trust him!Erick_Cantu wrote:Rubbish. ;-)nigelb wrote:When Chicago gets snow, it is usually very cold so the snow is like powder and that is why they can drive in it easier than we can in the water-laden stuff we get here. Anyway, that's my excuse and I am sticking to it!

Powder very quickly compresses into ice as it's driven through which is exactly what happens. It's worse at intersections as people spin their wheels instead of properly controlling torque. The snow melts, then refreezes into... you guessed it... ice. This variety (and the kind that forms from snow melted from exhaust) generally becomes black ice - everyone's favourite.
Driving home in a blizzard on bald tires is hell. :o
