One of the joys(?) of YouTube is that it can open new worlds that you are not really aware of. The current ‘new world‘ I am fascinated with is farming in Nebraska and Saskatchewan. I am use to watching farming take place in the small, tight confines of the English countryside and when you see the wide open and empty spaces of the North American prairie lands you realise what large scale industrial farming really means. We really do live in a small island off of mainland Europe. The North American prairie is flat and the farms and especially the machines they use are huge. The capital investment must be equally vast.
To give you some idea as to the size of these places Nebraska is roughly a quarter of the are of the island of Britain and only has 1/60th the population. However, when it comes to vastness this is nothing when compared to Saskatchewan where the area is roughly 4 times the are of the island of Britain with a population of 1/65th.
So YouTube is a vast repository of highly variable and questionable content in amongst the crap there is some really interesting stuff. It is just a shame you have spend so long trying to locate these nuggets of sanity.
