Here is an interesting deal for the St Louis area!
$99 for a 2 hour animal show (reg $200)
During the one- to two-hour Campus Critters experience, Burly Woods, an animal expert at the Wyman Center, gives kids a hands-on introduction to ordinary and exotic animals found in the local area. Woods caters the show to large or small groups, spouting off animal facts and demonstrating the correct etiquette for shaking hands with a snake.
This looks like it would be fun for a unique birthday party or for a school.
