Ex military buildings at discovery park

Well the military has gone and some buildings in great shape with desks chairs and tables remain.
These buildings are in perfect shape, for now.
Doesn't take long to have a building begin to succumb to the nature outside and lack of human activity inside.
The energy is gone that perhaps once kept the nature more at bay.
It's like a border were it not maintained opposing forces no longer meet, the building can relinquish to nature.
I had a Danish friend who once told me that if buildings were left vacant and not made available for homeless to shelter within a certain amount of time,  the owner was then taxed.
I like this idea.
that  might make me a communist here in America or just as disgusting a socialist , but there you go.
