wow, I totally forgot about infiltration.org.

Thanks for that blast from the past man.

Yes, blasted through those tunnels in first year in 1958, steamy, warm dripping/hissing places. The Devonshire place(residence) cat often went there for warmth and mice etc.

I remember exploring these tunnels. It was surprising how far you could go. Pretty much anywhere on campus.

Yes, Museum at the North all the way to college and StGeorge - further now with new construction. They also added refrigeration with a chilling building. I was amazed at the heat huge volumes of books quietly oxidising in stacks 80-100 feet deep give off - and there was another hiding area - student carrels CAN fit 2.... if they are good friends..
