ALERT: BIG MISTAKE

Don't encourage it, Don't even talk about, don't sing about it (cummbaya) - just don't do it, not worth the major danger you will put yourself in and you won't be able to greet any little green little men either :-)

Yep, ed, way wrong move on their part. I hope at least a few of the smarter ones will stop and read the warning signs plastered all along the perimeter, esp. the bit about "Deadly Force Authorized".   I know THEY want to know if there are alien beings there, but they first need to know an M16 has either a 20 or 30 round magazine and the rounds "tumble" when they hit flesh.   

I would bet this is yet another Facebook hoax, but I also expect some won't think it is.
