I allowed a Timber Faller to take his dog with him in the back of the cabin. We didn't have the choker ship that morning. He said the dog always went with him when the choker ship put the crew and fallers out to the unit. I made the mistake of letting him. It took half a day to get all the dog shxt out of the helicopter and a week before the smell went away. Only time ol'Schumer has ever been on the right sight of an issue.
