My wife, son and I were up @ the observatory on a Friday night a few months back. Little crowded in there. Pretty cool displays for those wondering how seasons work, tides, what surface of sun looks like...etc.
My friends and I used to go to Lasarium deal all the time in Golden Gate Park up in SF.... back in the good ol'
high school daze. It was always Pink Floyd that the show was set to.... usually a combo of tracks from "Meddle", "Dark Side" and "Wish You Were here"....... always a trip. I can remember many nights of going comatose in there and waking up when it was all over... "where is everybody?"
