The only good thing about the 70's I remember was Olivia Newton John's voice, and you were lucky to have a Scooby Doo lunchbox, mine was Flipper the dolphin.
Other good things:
Kolchak the Night Stalker
KISS Meets the Phantom of the Park (stupid, fun film, changed this ten year old’s life)
cheap concert tickets
good music
Most of the Florida coast was still wild (at least where I lived)
tv before cable happened, and really cool local stations that still had their own hosts (and horror hosts!)
