Life expectancy of the D80

Back in June 2009 (http://photonfarmers.blogspot.com/2009/06/d80-actuations.html) I made a reference to this website that records the number of shutter actuations of various DSLRs before the shutter died. I thought I'd capture it once here so in case the site disappears I have a record of it. Make sure to visit the original site for the most up-to-date data.

Invasion of What?

What are these bugs? I've never seen them before. I saw them at my parents' place the other day. Lots of them in soil or grassy areas.
