Fallout 2/Klamath (revisited)

Quest Experience/Reward Table

 * Find Smiley: 1000 XP, $100
 * Kill Geckos in Wilderness: 1045 XP

Details
Once you are in Klamath, talk to Ardin Buckner, and then tell her that you don't want a reward. She'll give you $100 anyway. Afterwards, talk to Smiley, ask him if he can tell you the tale of the Gecko, and then ask him how to skin Geckos. Now, with your new-found knowledge, go to the wilderness, and kill all of the Geckos there. Be sure you get their pelts. After you have killed them, leave for the Den.
