I know I've written about visiting Reptile Garden's earlier but it's a favorite Black Hills destination of the kids. Also, our most recent visit included the gator/croc/caimen show and some outdoor exhibits areas that are only open in the summer months.
#1: Mini-Mount Rushmore or giant kids. You decide.
#2: I spy a lizard.
#3: How to wrestle a crocodile and live to tell about it.
#4: The croc they got to touch.
