I wonder with the changing World we live in and more security concerns, that non-physical caching is the way that GC is heading.
I was speaking to a reviewer at a normal Event and he was asking for cachers to make valid comments known to GC if an Adventure Lab is poor, as they want to set a good base for these and to weed out the poor ones.
Lab caches have been going for some time now but still not fully included in your stats
Now we have Adventure Labs, still in a testing phase but how long will this last or after the failure of the Challenge caches (which were wiped off the whole GC system), are they being very cautious.
