Comments:

A challenging QRP experience:
1) Disturbed ionospheric conditions with quiet sun solar flux values;
2) Another in a long series of "unusual" massive winter thunderstorm outbreaks
   over the middle of the continent, drifting slowly east during the weekend;
3) Failure in tower-mounted antenna switch caused infinite SWR in 20 meter
   feed on 5BA around 0100Z on Friday evening; forced to use C3S at 20 feet on
   20 meters for the rest of the contest;
4) Rotator on 40 foot tower won't turn until the temperature rises above 60F,
   which is around 11 a.m. local time each morning; park C3S facing east each
   evening after 20 meters dies.

It can only get better: 
The tower maintenance is scheduled already and the next sunspot cycle is
beginning.

Thanks for the contacts and see you in the WPX CW contest.
