I have not yet seen the ISS, but will probably look for it soon with my 5-year old daughter.
One of my strongest childhood memories is of watching the
Echo satellite go overhead from my grandmother's backyard during a summer family barbecue, probably sometime between 1966 to 1968 (though it had been launched in 1960). Everyone was aware it would be coming overhead so we were all waiting for it -- they must have announced it in the paper or something for our area. It seemed a very bright star and passed completely from horizon to horizon in what must have only been a half minute or so -- way too fast for a high altitude plane, plus it didn't slow down as it got closer to the horizon. Hopefully seeing the ISS will bring back this memory in better detail. Even more hopefully my daughter will have the same sense of awe I remember having when I saw Echo.
While I wouldn't mind being younger, I do feel sad for today's generation, I don't think they ever get the sense of the fantastic we experienced so often in the 60s and 70s from our space program.
BTW Apollo 11 landed on the Moon on my 11th birthday and Viking I on Mars on my 18th... if you want to do the math to figure out hold old I am. This probably helps explain why I can't walk into the Smithsonian Air and Space museum without a bit of a chill or having to strain from keeping a tear or two from leaking from my eyes when I think and see how bold and glorious we once were as a Nation.
