Don't Poke at the Bear!

Don't Poke at the Bear! is a unmarked quest in Fallout: New Vegas.

Walkthrough
If the Courier has not allied with the NCR or done anything to decrease reputation with the NCR faction, they may be randomly met by three NCR Rangers. The Rangers give the Courier three days to begin an alliance or improve reputation with the NCR. If they do not improve reputation after three days, the quest fails and Don't Tread on the Bear! will begin.
