Lakewood Hospital

So about 10-15 years ago they closed Lakewood hospital and tore it down.

Now it's just a big grass feild, with no signs of future building, but it's all blocked off with fences.

Why?

If you're not going to do anything with the land, put in some swingsets, and monkey bars. Make it a small little park for the kids. Maybe put some bushes in, some picnic tables.

The land isn't flat, or else it would be a great place to play football games.

Why let the land just be abandoned but blocked off?
