In short - a very positive experience. Arrived around 3 and stayed for an hour. There were many people around - some in the water, several under the trees. No screaming, people talking at conversation levels. Virtually everyone was textile. Just when I got in the water, one of the guys, who turned out to be nude, left the water and proceeded to toss beers to his friends. He then asked if I, sans clothing, wanted one, which I accepted. I guess us naturist need to stick together. Even the beer guy's ladyfriend, after seeing me, felt comfortable enough to remove her top. While it was one of the largest collections of groups (6 or 7 making a total of probably 25 people), I thought everyone was respectful of the others.
Finally, I want to thank who ever has made an effort to shore up some of the less stable sections of the Bradford Ridge Trail. I thought the trail was noticeably less treacherous.
