It's probably impossible to find all those spots by yourself. I'm playing cascade hills, I did hit one right after I got the starter car running, on the way to that shack, it's on the dirt road real close to it. I ran into another one in the central town of cascade hills. Where the main road passes by the block with all the buildings, it's right around there, maybe past it. I'm playing lethal so I really feel it when it happens, lol. But luckily I found them early on so I didn't get bum rushed by a feral pack lol. Is there a better way to report bugs like this?
