I chose OPTION 3 - Try to turn to the right and follow the fence that way.
I have: a loaded pistol (11 rounds); backup food supply (beef jerky); water purification tablets
I must eat prior to the end of Day 5
It's really just a gamble. I don't want to meet whomever is making that noise, friendly people don't make a racket like that. Crossing the fence looks like a good option, but maybe it's there for a good reason? It's really just left or right, and I hope "right" is the right choice :P
