Central Texas had a good show this morning: it was either a meteor or space junk (possible from the collided satellites)? A Discover magazine blog is covering it, and you can watch more video here.
You certainly don't want to be hit on the head by this stuff.
And some doomsday scenarios are not supported by science :) Is this related to my previous post?
Bonus: the DVD of the Big Creek/Huntington Lake episode of California's Gold is available. You might be able to catch a rerun on your favorite PBS channel.
