Definitely the explosion of micro caches with no challenge in a mundane spot and here in Northern Australia the map is covered in them. The most pristine 20km drive from Cairns to Port Douglas has a cache every 500m stuck in the guard rail on a very busy road??? Verifiers need to start screening these more asking perhaps why are you putting this there? View ? Memory? Activity ? Not just so I can own 40 caches. Hats off though to the original members who got me hooked on this game with amazing puzzles, awesome containers in unreal places ..
