@RustyCrab if you go to the homestead with the forge, then go up the hill behind it to the right, then go left uphill more and keep following the path, there's a prepper cache there. no guarantee it will have anything in it but it could also be a gold mine
I'd check that, then go back to mystery lake because there are like 6 spots you might find a gun I can think of off the top of my head. or if you're close to mystery lake just go back first
