After re-reading your original post, if they really had bad intentions, and there were 5 of them, why didn't they gang up on you and take you to town right then and there? You said you interacted with one of them? If they were really "bad ass" the others would have jumped you when you were talking to the one of them. Maybe it's more innocent than I originally thought. BUT... still a wake up call and maybe a good one (no bad outcome) to have had.
