All the years I lived in Florida, it never got "old"... if I was home or somehow in a situation to watch the sky, I'd always go out to watch it. Even though it was miles away, depending upon which way the wind blew, sometimes we could hear (or at least we imagined we could maybe?) the sounds... going and coming though, the sonic boom was plenty loud for all of us, shaking and rattling the windows, hung pictures and the dishes.
There are two launches I remember the most though, one because I was so irritated, the other because it was such a special moment.
The irritation was that it happened that I had to take my grandmother to the airport at Orlando, the drive brought us right to the same stretches of highway used by folks heading to see the launch. The traffic wasn't such a big deal, we get used to it... the thing that was new to me was the tourists who suddenly applied the breaks to park "right there" so they could watch it when they noticed what was going on. I don't begrudge their desire to see it, they really could have done so in a safer way though.
The special one was when Senator John Glenn went up in Discovery. I was working that day but my boss and I went out to watch the launch. Somehow it was amazing, the glow of the rockets brighter maybe, the sky had a strange quality that day anyhow, perfect weather. I just stood and watched with tears rolling down my cheeks and even now, I can't say why I was crying, it just was THAT special.
