I would be thankful to all the CO's that have shown be beautiful and interesting places I did not know, a richdom of new experiences I did not foresee. I have also been inspired to do that to others, too, by laying out hundreds of caches in our mountainous neighbourhood.
If geocaching disappeared? I would probably look for other sources to get and share such information. Until I started geocaching, photography and Flickr was my great hobby. I would probably go back to making more photos, and take advantages of all I have learned through geocaching.
