well, i dont go to VA Tech anymore nor do i have a map. but i just wanted to inform you that VA Tech has a fairly complex grid of tunnels. some of the tunnels lead to the old stadium as well as an old library [ i never found the library ]
unfortunatly after going down into the tunnels the second time, me and my cohort got aprehended by the campus police. [ long story ] so we never 90t to fully explore. the tunnels go down at least 4 floors and it can get rather wet in places. also whoever goes down in them pretty much has access to any building they would like to cut the lock to get into.
there are a lot of sub tunnels as well.
