And Ihave a question; can you find Chance's body anywhere on the map?Or his grave? I know you can find his map (And I think I heard something about getting his knife, too.)

You can find his grave if you're willing to fight the bees.

Yep, you can find the Grave, the Knife and the Map.

Only two of these are in the same place, if you think about it, you'll know what two and where to find them.

To pile onto this, Chance's grave is on a hill left of the Tribal Village entryway (Assuming you're coming in from the road north out of Goodsprings.)
