Just as anyone going to or from. You'll probably understand quite fast if they are hiding something or not, depending on the answer they give. I
stick to the waterline-theroy though
Anyway, go there and find out!
Btw: Doesn't almost every city have city plans of all over and underground public and official buildings and structures? I believe these
drawings/maps are available to anyone who asks, either @ the library, internet or some city officials. If this round thing is just a simple
"nothing" it would most certainly be on the plans or maps. If it's NOT there, it's a little more interesting. Just a thought...
