I mentioned the existence of the "Plague Cemetery" to Tam at the BlogMeet yesterday as the marker is quite near the Dental School where she's been spending some time. I get the feeling that there's a lot of dead people underneath the IUPUI campus.
It reminds me of the Men's Hostel of the Central Hindi Institute in Agra, India, where I spent a school year back in the 70's. Rumor had it that it was built on a Muslim graveyard and that the maalii (gardener) was regularly disinterring bits of bone. A friend and fellow student even claimed to have confronted a pret (ghost) on the roof.
