I've haven't been a super dooper regular at the 'springs', but I haven't encounter 'wierd things'. However, the behaviour you experienced is why I am having so much difficulty in trying to get my wife to participate in public naturism. Unfortunatly this is a set back. Yes, I know one bad experience isn't supposed to the indicator, but in a case like this it sure seems to.
Sagebrush, I hope you don't ever encounter this again.
