We can chat off-line but the short answer is you need humans who want to work outside, in the dark, with loud high pressure water and air…and who will walk down steep terrain in moist cold environments under the guns. It’s not easy and takes a dedicated person to want to do that in 12-hour shifts. That’s one where pay scales will hopefully catch up to the need, maybe they end up like skilled tradesmen. But that job can be a hard sell to many in todays society.
