Back in the 1960's (and I guess since 1907!), after your visit to Knott's Berry Farm, you could walk on over to the Alligator Farm across the street and have some reptile fun!
I've been to one of these "farms" in Myrtle Beach SC and it was pretty amazing. I'll never forget the sight of whole raw chickens being tossed into the gator pits, wow, that exciting!
Disneyland made it on the Alligator map, right off the 101 before it was the 5.
