I live in Titusville, FL, across the river from the Space Center.
It was one of the few times it had gotten to freezing in Florida, so everyone had turned their sprinklers on over night to make icecicles in the trees and such. My family and I were in the front yard that morning, playing in the ice and watching the shuttle launch.
Granted, I was 3.5 years old, but I can still recall seeing the shuttle split in the sky above me.
