I remember when we first viewed that video *seems like yesterday but it was 2 weeks ago!*....The hazmat type suits caught my eye....*white* ...usually dealing with chemicals &/or *don't even want to type it* remains or fluids/tissues....
The more I watched this tho....the more I realized that they didn't tape off the area...they didn't seem too excited....they walked away after this in the video...
As to what is probably grown there....being only 40 acres....I'm guessing it's not a for profit farm...let's face it...unless you are growing money trees you won't make much on 40 acres....hobby farm...maybe....
I'm guessing they go haying every couple months....and probably sell the hay or trade with neighbours......it's basically a crop you can just 'let grow' ....notice the horses watching next door.....could be a few neighbours who could use the hay....
As for these matchy matchy buildings.......the one with the whirly turbine on top......I'm guessing pumphouse....sometimes sits on cement....all that will be in there is the pump being housed....a few mechanicals...whatever needed for the pump for the water system....As for the 2 matching smaller sheds...it looks like bags in there......and when we lived on the farm....we had extremely hard water......we used a water softener....takes a lot of softener too ...those bags are probably bags of softener salt......yes....salt......usually stored with the pump/water system ....if they are as I figure....then in that shed along with the pump could be the softener....Just google water softener commercial *bigger is better on the farm!*...and you'll get some idea what they look like.....
