Modoc Main Street is the central part of Modoc.
The Main Street contains the store run by Jo, Grisham's house, the church, the well, the slaughterhouse, the tannery and Balthas's house. At the center of Modoc by Jo's store, is a well. The player character is able to open the well and climb down it by using a rope. At the bottom of the well, are multiple bags of $1 NCR. Taking them results in a -1 karma loss per bag.
Modoc Main Street appears only in Fallout 2.
