The feeling of being watched in Pend Oreille County, Washington

My friends and family and I were Kayaking across Sullivan Lake in North Eastern Washington. We had spent the entire day slowly making our way around the side of the lake that is unpopulated (there is a highway on the opposite side of the lake). We "beached" at the far end of the lake where there was a small campground/swimming area, and it was there that me had lunch and let the teenagers swim and mess around. All of the adults felt very uneasy as if we were being watched and we made sure we kept the families close together. When we had to use the out houses we walked together and returned quickly to the beach. As we were beginning to leave the beach several of us noticed a rope swing on a very steep bank of the lake only about a hundred yards from the swimming area. I was among the last ones into a boat so by the time I came to the area of the rope swing, the others had already passed it and were quite a ways ahead of me (approx. 200 yards ahead). I was just daydreaming and enjoying the scenery, ( and to be honest with you glad to be away from the uneasiness that I had felt at the beach )when a movement caught my eye near the rope swing. AT first I couldn't focus on what it was and it took me a moment to realise what I was looking at. There next to the rope swing on a stump sat an old man.He was very tall and dressed in grey from head to foot.( My own father is 6'6" and I remember thinking to myself that this old man must have had him beat by at least 10 inches!) His legs were crossed and he had his hands clasped in front of his upper knee. I smiled and waved to him as I floated closer to him. He didn't move. He was tottaly still and watched me very intently. AS my boat passed in front of him (about 15 yards), I realised that this man wasn't wearing any clothes at all and he was covered completely with a very thick silver fur! Even his eyes were almost completely hidden from a thick (eyebrow?)of silver fur. WE stared at each other the entire time I passed by him, myself with my jaw gaping (I'm sure), and he just quietly sitting very still. AS soon as I looked ahead to see where everyone else was at and then looked back toward the rope swing, he was gone and just the branches of the bush that was near it was moving. I have never seen anything like it before in my life. I thought I was honestly seeing things until my niece pulled me aside later that evening and asked me if I had seen the Sasquatch that was sitting by the rope swing. I honestly have never really given much thought to Bigfoot before that day. I had passed close enough to him to actually see the direction the fur was growing in! It was mostly all one direction (down)like a dog's hair, except around his eyes were it seemed to stick straight out.
