Of our 8 trackables, one went to USA and died, one did not survive a newby visiting the original cache that it was placed in, four have gone missing and 2 are still moving around. The four which have gone missing can all be tracked back to people who have only visited a few caches. I dont think newbies know what to do with trackables that is why it is so important to attach instructions to them.
We are reluctant to send any more out to their doom.
