Cherry's Freedom

This is a minor quest. If you talk to Cherry, one of Dukov's escorts at Dukov's Place, she will ask you to escort her to Rivet City. You can just leave Dukov's and use fast travel to take her directly there. The reward is a Karma boost. Also, you will be able to find Cherry wandering around Rivet City after the quest.

You can use this escort as incentive for her to steal Dukov's key for You Gotta Shoot 'Em in the Head
