Old Johnny Quest was awesome. So was Space Ghost (not the adult swim one. The actual cartoon). I watched the fuck out of both those shows. And the Herculoids... and Birdman... Now I'm depressed.
I think im a tad younger than you are. I never watched space ghost unless it was on boomerang.
I hit the ground running with G1 transformers, thundercats and all that shit, but I still get a kick out of Johnny quest, even now. That shit just doesnt get old.
