I would not be discouraged you will find them, and I plan on doing a really nice write up for the community on everything I have learned about them... Even if you know their loc's there are 20 per zone or so. That will help you not to miss a location but even then they are very hard to spot. So it is really easy to miss them..But the two we have found are pretty neat. You kind of think of them as your little buddy. I want to spend another week hunting them so that I write up something helpful and not something that is not useful for folks.
