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.
