Kondor: Not a problem that requires solving but I just want to point out this problem so others can avoid it. If you go up to the gates of Junktown at night a guard will warn you to put away weapons and will also tell you that Junktown does not accept visitors at night, not only this but the guard will instantly become hostile (Yes it is a very bad design flaw) and will attack you. To add to this, you get this problem when you are LEAVING Junktown too! If you walk out the gate at night the guard will give you the same talk as if you are entering and will become hostile. To prevent this flaw from affecting you, only enter/leave Junktown in daylight hours, if you happen to be inside Junktown when it is dark, just use first aid on yourself or your dog or rest until it is day time and then you can leave.

Weclock: Alternatively, if you have your weapon out, and you are asked to put it away, there's an option (the nicest option available) where you apologize and etc, and if you go through that little bit first, he's more likely to let you in at night, because he sees your moral character.
