LOL! That cracks me up!
Best was when my section chief asked me what our site to crest was, I referred to my notes, and he looked at me like the world was melting.
He then showed me the chief's board 'safety t' that showed the min elevation being below the site to crest I'd rattled off.
We sweated that for a few minutes, got a fire mission, min elevation.
We had to be pale as that nice smooth copy paper as we'd asked FDC about it and they said "Don't worry about it. FIRE!"
Top branch and some leaves fluttered to the ground 100 meters away.
And then we sighed, and got comfortable for the next several rounds.
Of course, we cracked jokes about doing alternative logging techniques with the howitzers.
