How many TC's is too many TC's? Answer inside.

It's standard height, but 825 sq ft. It does share space with my shop and some vehicles are on dollies while others only have two wheels, so I make maximum use of my space. My DW sometimes looks at it shaking her head. She asks me what will I do with all this if you die? I tell her: It's up to you, I won't need these things anymore.
