During my most recent visit to my place, I sat in the center for about 20-30 minutes. I noticed that while I listened to the wind rustling the leaves still on the trees, there was background noise coming from the highway. I could also hear a tree creaking, which I found was coming from an area at the edge of my site, but I couldn’t figure out exactly which tree it was. It was a cool day, but I was still comfortable without a coat if the wind wasn’t blowing too hard. There was a yellowjacket sitting on a fallen leaf near where I sat, for the entirety of my visit.
