You really don't see the problems with a sport until you get deeply involved in it. As the one that has placed the most stashes so far, I began to see the problems that it created. Some of my stashes are placed on tree farms owned by a large corporation. They are not, No Trespassing areas but they are private property. I didn't think too much about it at first because woods is woods around here, and a cache bucket seems like a pretty benign thing. The problem I saw was with the published coordinates attached to an uninvited bucket attached to my name could some day cause trouble. Some corporate dude five years from now could decide to prosecute me for littering or something just for the fun of it. For that reason I've decided to remove the stash buckets but keep the coordinates that are interesting for another game.
The second major problem I found with geocaching was that you couldn't easily place them in urban areas or other areas of special interest. One of the goals I had for geocaching was to attract people to some of those "special spots" that only local people know about. I know of many unique spots in the urban area that I would like to identify for people to visit. I tried the CyberStashing concept that seemed to solve all the problems, but that was a flop, it was too complicated.
So now I'm on to the Wondert game. Looking for places where just being there is the reward. I think it might work, I'll let you know when I get back from vacation. I know my Billy Graham stash would make a good Wondert and probably Williams Lake too. The two cyberstashes are certainly candidates. I'll see what other Wonderts I can find.
