Hi Pat,<br>
<br>
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!<br>
<br>
I mentioned to Murray that living in Texas, my body is well adapted
to radiating <i>away</i> 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. <br>
