Gordy as usual was spot on!
You NEED to walk or drive around EVERY field in order to check for wires.
If you do nothing else he says....do not ignore the wisdom in his statement about wires.
The Big Wires are fairly easy to see.....the small thin skinny ones hung low above the ground, Poles hidden by trees, ending at pump houses and other farm structures and devices, are Killers!
Even if you do the Recon by Air.....before you jump into a field for the first time....go very slowly around the perimeter and then work your way in to the center looking only for Wires, signs of wires, anything on the ground that would have a wire attached to it...running to it....running from it....as those wires are the single worst danger to crop work.
Wind speed under the Rotors is more dependent upon forward speed than height above ground. A high hover will produce a higher rotor downwash than if in translational lift or above.
Drying Cherry Trees we found a higher, slower movement through the orchard gave better results than a very low speedier movement. We were only wanting to shake the trees enough to shake the rain water out of the dimple where the stem goes into the Cherry.....but without breaking limbs off the tree.
