Tunnel

A pool of water.

And a mound of concrete.

A would-be assassin holding a grenade.

An entrance.

A long way down.

Is that the bottom?

Is that the bottom?

Words in foreign languages.

Water.

This is down below.

Watch your head in various languages.

Down there is the bottom.

The way I came.

This image blurred a bit too much.

Well at least you can see the flags.

Caution-A-Hole.

Another exit tunnel.

This tunnel used to be closer to a cylinder but they built this platform over where the trains will run.

This is down at the lowest level. If I'm right, that tunnel runs under HBC.

Not where I came down.

I decided to not go farther than those pylons, to avoid a big puddle.

Looking back the way I came.

Another tunnel contraption in the larger part.

Time to head up.

Looking back as I go up.

Nearly at the top.

The way up.
