Wow....I read "Littleton" and "Shoot"...and my heart just kinda froze for a moment. You might want to re-think your wording a bit.
Well, it happened at Columbine, which yes, is in Littleton, but that's never how it is referenced. I live very close, lived through the insanity and it isn't an issue for me. So, let's not worry about that.
