I've been there a few times but never looked at sites with the idea of a group hang. So wherever is fine with me. As far as privacy is concerned, I don't expect there will be a lot of people out there.
If anyone is interested in hiking, we could hike on Saturday to Egge Lake and to my house on Sunday (between Hwy 6 & Hwy 1). I'll have a car there and it's around 10 miles back to Crosby-Manitou.
