I wouldn't "pre-find" the cache, as part of the experience is, well, finding the cache! The demo will not be authentic if you know where the cache is located.
So far I have found every cache I've tried to find. My understanding is bad waypoint (i.e. wrong datum) is the biggest problem to finding a cache. I like the idea of having a few caches ready to hunt to make sure you at least find one.
As an aside, I used to try to find the reference locations in the NGS database. These are tiny markers in the ground, sometimes in a PVC tube. I have stumbled across more markers than I ever found using the database. This was in the old SA days, so maybe my luck would be better if I tried again.
Here is the link: http://www.ngs.noaa.gov/datasheet.html You do a search around a coordinate, then pick a spot that has potential.
