Big Town's: Big Infinite XP Glitch, and Free Stuff
Before you read: I've tried this it works you just have to do it right, OK? Save before-hand.
1) Go to Big Town, and find Pappy, the guy that watches the ladder bridge leading into Big Town.
2) Pick the dialogue choice, "You came here with Bittercup right?": If the choice isn't there, find Bittercup, and talk through all of her conversation choices. Speak to Pappy again, if your Speech skill is high enough {Speech 100%} should appear next to the dialogue choice.
3) Now selecting that dialogue option with success will get ya 6XP. Do this over & over for however much XP points.
Free Stuff from Bittercup
If ya want free stuff from Bittercup, you have to agree with her and put super sweet to her. If you do it right she'll give you an misc item, ammo, aid, ect. Each time you leave Big Town for awhile. To get the free stuff just talk to her.
