It's a bird! It's a plane! No, really, it's a plane?

I ran in to get the camera when I spotted a Broad-winged Hawk circling overhead. By the time I got
back outside, he had flown some distance away. I looked up and saw a silver glint and two contrails.
Then I heard a small plane, but couldn't see it. It was getting closer, and all of a sudden it flew
by, about 2000' up and climbing I would guess.

I ran a check on the registration number and think that it may have been part of a raccoon rabies
prevention bait drop.
