The trackable situation is kinda grazy at the moment.
I´m relatively new with 78 finds and 8 Tb´s moved so far, but I saw a lot of Tb´s dissappeared, some were logged at a different cache.
I write many notes for missing Tb´s (one of them was discovered again after months a couple of hundred kilometers away from the last known location),
I saw a cacher who allegedly took a Tb to more than 100 caches in one!!! day, other cachers dip them every 200 meters for weeks or months,
a Tb hotel near my hometown with 7 Tb´s in it got compleatly emptied, you name it.
I want to send one or two Tb´s out myself, but oh boy.
This really makes me wonder, if it´s a good idea to make the Tb´s / Gc´s a premium member only thing.
