GREAT IDEA! This would take care of all of my current problems!
I'll build a block wall with thick windows in it IN MY BACK YARD.
I'll throw some moss in it, plop some endangered fish in there, and sell them on the underground market as a dellicacy, hehe.
No more dog problems, no more money problems. If the dogs break through the fence, I can flood the neighbors back yard with slimy moss!!!
