Megan, I am so sorry!! I know how unsettling these things are, even though they turn out to be a hoax. I couldn't believe it when I read your post because the very same thing happened at Kayla's [16 yr. old granddaughter] high school in Oxford, Alabama yesterday!!!

I think this is becoming quite common although we just don't hear about them. It has happened so often at Kayla's school the last few years that now it's just an aggravation for them ... but we are so thankful that the school system takes every single crank call seriously!!
Just tolerate it and always, always follow their instructions ... maybe someday those sickos who do this will just crawl back under their rock!!!
