...that is, kind of, my point. I spend a great deal of time investigating the blue circles and finding the same things over and over again. If FD intends for this to be the way to find them then that is fine... however, if they wish to clarify and somehow the answer is that they do not show up in POIs that can be seen as blue circles on the radar at 1.5km and higher altitudes but must be visually spotted then it would be very helpful to know. Either way is fine but it is ambiguous now as to which way they will be found.
I hear you. For some of us this is actually part of the mystery and accomplishment of finding something rare.
Some wants more clues, some doesn't. Probably why they are careful not to spoil too much.
Personally I like it like that.
We know we can find either types, we just need to keep looking.
Not sure whether you remember the UA hunt that went down from March, within May finding one, in July finding another, and so on.
Once you find one, you will start figuring out more.
This time though, you may be able to find a static one, one that wont go away. IMHO it should take a bit of effort to find such a location.
