I was There
I spent the night in Littleton on the way to L.A. from Chicago.
And, yes, I did see the high school where those terrible shootings took place. I was there just 6 months later. I was riding a bike around the school, and was just praying for the kids there. Then, this security person got all upset and said I was "tresspassing". I was just leaving the parking lot on the bike, that's all. Yes, there was still a lot of fear in that place.
