I was out on my first bounty hunting mission, tracking some idiot down who had been poisoning people, when some guy came trotting past on his horse... I hailed him and he grunted something, so I hailed him again and he reined in, spun his horse around and drew his pistol.
''You trying to get shot'' he growled.
I slowly reined back and he just grunted again, scowled and turned around and rode off muttering to himself.
Not everyone is friendly out there... you never know what might happen when you meet any strangers.

I've stopped a few passers by as I go along... not had the same response from anyone yet. Which is quite refreshing!
