I spent 54 years as a journeyman truck-and heavy-equipment mechanic, often working through the night by myself a long way away from any help. I am amazed when I see things such as equipment operating for long periods without a sign of a grease gun or any maintenance at all! A season or two ago, an excavator chewed up a final and Jack took it apart, and it was obvious that it was bone-dry without lube- no wonder! Does anyone there ever check fluid-levels or grease anything? They seem to just jump in and go to work! I don't see them winterize anything, yet they come back the next year and wouldn't you know? It fires right up, and again they go right to work with it! Amazing equipment, huh? This year Todd and Jack take over an existing claim, and wouldn't ya know? Somebody left equipment there! Another miracle- the batteries are hot, the stuff starts right up without anyone checking a thing. Hells' bells, the Teletubbies have more smarts! I have to add one more thing... the narrator has a death-wish outlook! If something minor happens, suddenly we're told "If they can't fix it, all will be lost!" C'mon, get real. Take care of it and keep going.
