Hi Yizhe!
Have you done any geocaching on your own yet? I believe if you did, you will love the game and maybe relate to what I've to say. But if you haven't, then maybe it's something to consider doing before planning a project on a big scale. That way, you will realise the importance of preserving the beauty of this sport.
I agreed with javamama that geocaching in Singapore is pretty much a self-organized and regulated community. Most geocachers will share the same sentiments that geocaching is certainly much more than a 'treasure hunting game' with attractive prizes and big organization companies involved on a massive scale.
Other than the thrill of finding a cache, or a dose of healthy first-to-find competition, being at the location itself is always worth much more than the prize on stake. Not to mention the rare occasion of meeting fellow geocachers at caches' sites!
The sport and rules of geocaching has been established at geocaching.com. Having read the rules of the sport extensively before starting the sport myself, it will be good to emphasize some points...
Firstly, geocaching if done improperly without proper knowledge of the game and rules, might actually bring more harm and disturbance to our natural surroundings. Hidding a micro cache in a natural plantation is certainly not a good idea, groups of primary students might do a bushwacking to get to it. Even if the cache is not hidden there, anyone else will still do disturbance if they are desperate enough to reach a cache.
Secondly, the government can easily outlaw this game that we loved as easily as banning chewing gums. Promoting geocaching in Singapore the right way by reaching out to more participants first might be advisable as the first stepping stone before embarking it on a mass level.
If not, we might just find ourselves with film cannister caches sticking onto common lamp-posts just like what Ed had experienced in Arizona.
