I was just at Kennedy Space Center a few weeks ago. Lots of kids. While none would remember 1969 (Unix, Woodstock, and Man's first steps on the Moon), I did. The kids not interested in the exhibits were very interested in spotting alligators, armadillos and whatever on the bus ride around.
Too many pictures are here:
We were there a few hours, but easily could have spent a couple of days. Amazing how most tickets seem to be good for 2 days.
