A neighborhood of Georgetown in Washington, DC is called Book Hill where there is a hill with a small park on it.
I had passed by the park several times before, but only this afternoon did I get a chance to take the steps to the top of the hill. There were 5 or 6 beech trees in the park. Whenever I am near a beech I can't help myself from checking its trunk for feeding tracks of slugs. Sure enough, on a couple of the beeches I saw what I believe were slug tracks.
Now we know there are slugs in Book Hill Park, but I don't what species they may be.
Excuse the quality of the photos. They were taken with the camera of my iPhone.
