No trolls.....

....but there are some other animals spending a lot of time under the bridge. Their photographs are below.

When I first saw one of them, I thought it might be a beaver. I believe that is a pretty good example of what birdwatchers call expectancy bias. Where the hope of seeing a thing tends to distort your vision of what you actually do see. Scroll through the pictures and see if the same thing happens to you....

Don't forget to go outside and play.
