?????? Have you never walked on a log that has had it's bark peeled back? It's slippery then snot. Ever been to a GP papermill to pick up a load of paper, or to a sawmill that makes utility poles? Probably not since you have no experience in trucking, but I know you're smart enough to know that there are other processes in lumber that require a man to walk on debarked lumber. Not every log is so precious that even the leftover lumber used for stickers can,t afford to have little 1/8" pokes in them from the calks. Why you would even respond to my reply on such a basic question/answer thread suggest to me that either you have no experience at all in tree work (which I don't believe), or you have a bone to pick with me. I'm guessing you have a bone to pick with me...... Eitherway, I don't really care. 80% of the replies on this and most forums are to try and belittle the other guy to make one's self feel better, not to give a HONEST answer (good or bad) based on one's experience. Typical of society. I guess you couldn't make it as a chemical engineer so you decide to make yourself feel better and pick on lower educated tree workers since you know on a chemical engineering website you would look like a fool!
