Got buzzed before and after lunch by two Su-25 Frogfeet from the Armenian Air Force (I guess).
Remembered to make x-values and x-increments negative, as I'm in Quadrant II of my hypothetical grid.
I'm also getting this funky "USE MANUAL TUNING" error. It seems if I walk away from where I'm getting that error, it works, and I can even go over that area again. Weird. Oh. I could have been because I didn't plug in the staff.

Anyways, I redid 4C' of 2ºha, as well as doing 4D' and 4E'.
The prime means it's from the second hectare of a whole site, like Tsaghkahovit.
