Shytorque you mentioned the orange groves in florida. A colleague of mine used to:
Fly over gigantic orange groves in Florida between 15 and 30 feet above the trees. 45 gallon Diesel drums were set alight and the heat was spread over the crops to keep the frost away. They had to fly between 15 and 30 feet. Too low and they hit the trees, too high and they were flying IMC in the layer of diesel smoke.
All this was done alongside 20-30 other helos doing the same thing at the same time
Another job he did was to pick up half a dozen mexicans in the morning and hover over the croc swamps in Florida allowing them to jump into the swamps and herd the crocs away from public access points! His job as the pilot was to be at the ready to collect any of these 'volunteers' who were being chased by a rampant croc
Couldn't believe it.
