"I spoke with the FISO yesterday, and he recalled the occasion immediately .... it seems that on that particular day it was felt that the threshold was actually preferable being less wet than the area where you suggested departing from; apparently there is a tendency to standing water near the runway intersection. Agree or not, that was the reason, and with the best of intentions."
Slip, reassure me you were merely talking to the FISO and not airing that wonderful machine?
This isn't thread drift because in this wind, one doesn't need a runway...
