In 2003 i was emailed and phoned, and asked to remove two of these pictures.  It wasn't clear, but something about protecting the privacy or identity of someone in the pictures.  This strikes me a strange request - i mean, it's not like anyone is naked or doing anything illegal.  It's just friendly people hanging out in nature.  But, who am i to know what sort of paranoia lurks out there.  So, i have removed the images, leaving only thumbnails so you can't recognize anyone in the pictures.
