Throwing can be a problem. I was told by feller buncher and processor operators, Just throw a stick in front of the machine. We'll see the stick going across sideways and know to look around. Well, some of us can't throw worth a hoot. Maybe an atl atl or a flare gun contraption might work. Maybe a paintball gun or something. I do believe I could sail a hard hat but then it might get smashed "accidently" and I'd be unsafe.
The most memorable moment of "What the Hell do I do now?" was marking trees up to the landing, I'd talked to all the guys on the landing, let them know I was working below, they were setting up the yarder. About 200 feet below, on my way marking a strip up the hill, root wads and cull chunks start being thrown over the edge. I hunkered behind the biggest tree I was near--this is second growth so that's not a lot, and tried to figure out what to do. There was a lull in stuff coming over the edge, so I skedaddled and got away, then got up to the landing and made a super stink eye, and in a nasty voice, let the shovel operator know what he'd been doing. Bad...bad... bad and I wish I'd had the E-collar on the guy. Such is life...
