Majestic view from three floors up, I think F. Fwd building on UBC campus.

Not quite a rooftop, but a stairwell window in I think Sprc Hs building.

And for good measure, a tiny piece of the fabled steam service tunnels:

Sometimes doors just aren't securely locked. I thought for sure this was my entrance into the whole labyrinth, but this tunnel ran the length of a building, and had a ladder leading up to another short corridor, which ended in a sprinkler valve room -- as I learned by the sign after I left it.
