I know about the tunnels behind the cafeteria and possibly post office, but nobody says what the entrances look like/how to spot them. Same with getting on the Lee building or finding the attic to Montgomery.
I've been researching the more secretive places on campus and you guys post a lot about tunnels and hatches/stairways but never give any precise explanations. I'm dying to check it out but snooping would go way faster if I had some actual directions.
