I was wary of it right away. First, I don't remember ever entering any sweepstakes. Second, look at all the typos in here. US isn't capitalized in some places, check is spelled incorrectly in others and what's with all the different names. The check itself looks legit, but it's got Maverick Metal Trading for a heading on it. I looked online and Maverick Metal Trading and General Dynamics are both legit companies but have nothing to do with each other as far as industry goes. I and my husband actually called this 'Paul Smith' three times. The first time my husband called and he didn't get an answer. I called and it was a funny ring tone, some guy answered just 'Paul Smith' and he sounded like he was on a speaker phone and he had marbles in his mouth. I asked him what this had to do with and he mumbled something about a charity. He then told me to call back in ten minutes. So I had my husband call back and he then told my husband to call back in 30. That's when I decided to look into scams and sure enough, it seems this particular scam has been going on for a while in different areas of the country. So, take the check, tear it up and throw it away. Or, go to the police and let them know. I'm going to see about posting it to the local media. See if maybe they can put it on the air and warn others about it. I mean, in this time, what with Wall Street tanking and all, people can be desperate for money. I certainly can use more money and I was jazzed at first that this could be the real thing.
