pdxflint, I gotta say, you're made of sterner stuff than I, being able to leave her behind!
I'm obviously a dog person, but still, even just looking at this photo, I can appreciate you feeling that perhaps you shoulda' brought her back with you.
You shoulda'!!
By the way, it's fascinating seeing your results with these two p&s cameras. I've still got my crappy little 5yr old p&s, but my girlfriend has a D40 and even using it just the odd time, the difference in quality is obviously huge and so seeing stuff from more recent, higher quality p&s', is interesting.
