low angle photography of missile silo hole

I took this photo on my trip to cologne. I went there to meet with a friend I made through a designer chat that ultimately became a close friend group. Its so cool to imagine that I could easily have a place to sleep in Germany, Switzerland, France, England and Canada. We were going to a a parking garage to shoot on top of it but when we entered I looked up I immediately asked my friend for the 10-18.
