Money and prizes in caches... in How do I...? Posted March 6, 2007 · Edited March 6, 2007 by arpegio I imagine that people into Geocaching cross a wide variety of economic levels. I think it's great that people are leaving substantive treasures in caches. I wholly endorse this idea. Also, you know what they say.. One man's trash is another man's treasure. I'd like to see more people put valuable stuff they no longer want in caches. The biggest problem is the size.
