Holy Crap Thunder Batman! Dear lord have we had some wicked storms in the Chicago land area lately. Like 4 Horsemen of the Apocalypse type storms. I imagine that this is what one of the cloud's really looked like up there. Bastards.
Check this out from today's Chicago storm. The wind blew out a window in my building as well. Wicked.
And, check out these cool pics...right...HERE!
