Um.....there is something on the roof. Something BIG. And I'm not talking about our super-psycho-fat-squirrels that torture me on the back deck. I'm talking humans sized. There are loud noises and things flying off the roof and things being lifted up there....I don't know what is going on, do you? Don't get me wrong, I'm not askeered (its not Thunder!) but I just need to protect me house. What should I do?
