[David Anderson]

Hi Pat,

Yeah, I tried to shoot some video but camera needs charging.  I was 
outside for a total of maybe 10 or 15 minutes; too cold.   The stills 
are from a route it took down the driveway and around the cars and back 
up my neighbors yard, total maybe 5 minutes.   So no time trials today!

I mentioned to Murray that living in Texas, my body is well adapted to 
radiating /away/ heat.  Conserving it not really part of the equation.  
Currently 11 degrees F in Denton, expecting 6 over night and with 
howling winds the weather folks say wind chill of -20.

David
