Okay I'm from pretty much the middle of Wisconsin, and i have been to most of the zoos around me! I know for a fact that Milwaukee County Zoo still has Mold-A-Rama machines, But where else still has them? for those who dont know what im talking about... I know Brookfield Zoo used to, but i don't know if they still do... this summer we are planing to heading east to the Smithsonian zoo, a few in Ohio, Indiana, and that general direction. I have found a few picture of them from the Minnesota Zoo as well, but when i was there last year i don't remember seeing any. also Henry Vilas Zoo in Madison WI. used to have them but i havent seen them there the last 3 times i was there. if anyone know what im talking about and where else they still have them let me know! thanks!
The San Antonio Zoo has had them for more than 50 years - I still have one of a lion from when I first visited on my 2nd birthday (back when they exhibited Eohippus...) - and just made one this Spring when I visited with my niece and nephew.
The Brookfield Zoo still has some. I know of one at the end of the swamp and at the entrance to the Australia house.
