Ive got 13 balls and a 2.5 yr old girl...I keep them in my bedroom in a rack system, and a closed door. She knows her boundaries, and knows that the snakies in the rack are a no no unless Daddy is holding it... but do what you will. I dont recommend a garage especially one that isnt insulated. Thats a bad idea waiting to happen. If you convert over to a tub, Im sure you can find some room on a bookshelf or even your entertainment center or something, no? Either way please dont put it in the garage/ =P
