Hanna Barbera characters used to be everywhere. They were on television, at the movies (sometimes), on toys, cereal boxes and books. I can even remember a Dino the dinosaur toy "egg vending machine" at the bowling alley!
The H-B crew could be found at amusement parks, too (Kings Island, Kings Dominion, CaroWinds, Great America, Marineland, Canada's Wonderland, Australia's Wonderland, and Universal Studios Florida (and probably others). Fred Flintstone and friends have been evicted from most of these parks, typically by Snoopy or Nickelodeon characters depending on the time and location.
However, if you really want to see Yogi Bear, you can visit Shipp's Yogi Bear's Jellystone Park Camp-Resorts all across the United States!

I've been to Chattanooga (yes, aboard a choo-choo!), but I've never been to Jellystone Park. I think the idea is pretty clever.
It looks like there's plenty to do near this location...

I do wonder if there is a Jellystone Park souvenir shop. Maybe they sell Pick-A-Nick Baskets with Yogi's face?
