Nothing much goes on in the Upper Peninsula of Michigan and the people that live there (Da Uppers) have a difficult time adjusting to the American way of life.
I think we should perhaps put it on e-bay and auction the Upper Peninsula off to reduce the Federal deficit?

Hollywood has been preparing us for such news by our government. Hollywood has made hundreds of movies and tv shows and radio dramas on ET's, and there's been hundreds of UFO sightings th world over. In view of this, would we get scaried? Would the military try to shoot it out with the hostile races knowing they can't win? What's your thoughts?

On one hand you have fetuses being "murdered"

and

On the other hand the research can proove to be very useful for creating new organs ect that will help cure dieseases!

What do you think? Is using fetuses for stem cell research wrong?

I live in Philadelphia, PA. That's in the United States, for you outsiders who may not know. . .

I must say that for the past few days, the weather has been similar to spring last year in terms of temperature and humidity. I mean, you can easily walk outside in shorts and you won't get cold. And man is it HUMID!!! It's suppose to be freezing during this time of year but it's actually warm compared to what it's suppose to be like. It's 62 degrees F outside right now and tommorrow it's predicted to go all the way up to 70 degrees. How messed up is that?

Is there anyone else who lives somewhere where the weather is showing radical change?

PS. If you live in Texas and it's 80 degrees outside during the winter, that's normal so you don't count :)

In 1994, the year of the big snows, I saw two of them walking down by the creek. This was in the northern Appalachian Mountains. Panthers, as they are called aound here, are supposed to have been eliminated many years ago. The case against their present existance says that #1 There have been no road kills. #2 Hunters haven't killed any. #3 There is no physical proof - only sightings. In other words, they are akin to Bigfoot. But have YOU ever seen one in the wild?
