Not only that, but rain and wet environments, it takes a skilled person to keep everyone safe, and also be able to wrench on a large diesel engine...while starting at 3 am, wrapping 14hrs later. And in some large film unions, you need to pass a test just to get into the department, let alone run a generator.
