Park

Today when I went down to the park for the second time, it was cloudy and high tide.
When I was on the beginning part of the boardwalk by Sage Rock, I saw two people talking about a baseball cap that was placed on a rock just barely out of the water.
When I was at the beginning of the park by the visitor center, I saw a squirrel run up a tree that was out in the open with a bunch of pinecones under it.
When I was at the battle site bench, I saw some sea gulls out in the water.
When I was on the side trail near the trail by the river, I saw some more sea gulls.
When I was on the trail by the river, I saw some sea gulls and ducks on the other side of the river.
When I was on my way back, I saw three boys, two of them were down where the hat was and one of them was up on the boardwalk. Apparently the one on the boardwalk was the owner of the hat and had forgotten it there, or that’s what I got from what I heard while I was walking past.
When I was out on the breakwater, I saw a great blue heron on the harbor side of the breakwater and some people fishing in a boat on beach side.
Why was the squirrel at the tree out in the open?
Why was the heron on the harbor side?
Why were those people fishing so close with a boat?
