The buildings here were modern, efficient, and cold... repeating floor plans and empty rooms made for a somewhat disheartening trip. Access was easy, and it seemed quite a few people have gone through the place and thoroughly smashed everything they could.
Some shady characters walking around outside the building heard us inside, and offered us $5 to come out; I guess that could be considered interesting!
The tunnels underground were extensive, and had very high ceilings... I was impressed at the construction of these. The miles of steam pipes were grated off... I really hoped they didn't take the kids down there to traverse the campus.
