I agree wholeheartedly with your comments. I did, in fact mention some of the pros of geocaching, ie that my kids are now finding out much more about countries that they wouldn't have known about etc etc.
As you said, geocaching promotes healthy excercise and more interaction between families in the great outdoors rather than sat in front of the telly, pc, or whatever.
I am sure this nonsense will go away long before any of us geocachers do, but in the meantime I don't blame people for posting about how they feel and what they would like to do to the perps, me included.
