Very large disk shape, many portholes, silver in color, nestled between two hillsThe sun had already gone down and the sky was still lit up slightly when our family, two daughters and my husband, were in our boat and going in to shore. My husband was steering the boat and my daughters and I were enjoying the scenery. As I was looking tomy right, I did a "double take" because I remember thinking quickly that the arrangement of the hills looked different than usual. I saw an extremely large, silver disk hovering (no sound) in between two hills and the port holes, many of them, were clearly visible. It was suspended and I could see the remainder of the darkening sky around the edges of it. I said to my husband "What in the world is that?" As I kept my eyes on it I looked then at my daughters and I think they were looking at the shoreline thinking that I was talking about a pretty home or something. I looked at my husband and I don't think he heard me because he didn't respond to my question. I think the engine of the boat was too loud. He still looked straight ahead. Then the hill to the north began to block the disk and it went out of my sight. I thought I should ask my husband to turn the boat around but at that time I couldn't believe that I even saw what I saw. I never did say a word to him afterwards. I did tell my oldest daughter eventually. It's a difficult subject to talk about. I continue to tell myself that I didn't really see it - but I know that I did. The image is as plain as ever.
