LoL....20 tanks ....you are SO out of control. And Don talks about me. You do realize don't you? You are going to need more than one rack. You're only going to be able to fit about ten tanks per rack. That's why I went with the five foot wide rack in my closet. Im trying to maximize every square inch so I can keep everything on one rack. I look forward to seeing some new threads on some tank builds and frogs. We are going to be starting a new contest in July...be prepared.
