Also on the just go out and shoot front I dumped my card onto my computer
tonight and discovered I'd taken 400 and some pictures in the last 30 hours.
I was working on a couple of projects and ideas; alas many of these images
are dull and redundant but -- I do shoot.

Did I ever post my said pictures of the fallen pine and the four days of
blackout? Followed by the arrival of spring, coming in after that mayhem
like a late and overweight hero? Here they be:

http://gallery.leica-users.org/v/toast+eatin_+bog+man/  -- and go to first
gallery featuring the guy sawing the tree. All photos taken with G1 and
14-45 kit zoom.

For fans of Scrabble, the pictured game ended at 295 to 286, my favor.
Closest game I've played. With the baby and other trials of a cold cold dark
house it took three nights to finish.
