I’ve been to some “sketchy” areas, but usually just passing through. I can’t think of a time when I spent some time in a place and then decided to leave because of bad vibes. I remember going to a really sketchy hookah bar once but we stayed for hours. lol.
In a different sense, I was once hiking in the woods when I came upon some bear scat in a clearing. That freaked me out knowing a bear could’ve been around the corner (also there were thick trees all around, the place seemed like the perfect spot for a bear ambush). I quickly fled the area and went back to a more well-used trail.
