Barton the Fink

 is a unmarked quest in Fallout: New Vegas.

General
This quest is given by Barton Thorn near Goodsprings Source.

Walkthrough
Head to Goodsprings Source, and towards the water tub, you'll see Barton Thorn wandering around. Talk to him, and he'll plead for your help to save his girlfriend trapped by Geckos. He'll give you clear directions on where to go: head towards the broken radio tower, then turn right. There you should be going up an incline.

There will be broc flowers growing on the slope. As you go up, you should see a path forking off towards the right. There is a refrigerator, bed, and some loot (the optional cache). Be careful, however, of the three or four bear traps. This area is also a Wild Wasteland trigger area.

It is advised to kill all the Geckos on your way up. On your way down, Thorn will be right there carrying a pistol, revealing his clever ruse and turning hostile. Kill him for some loot.
