This thread has been both amusing and enlightening.
I log discovers/not founds on travelers, both coins and bugs, as there are far too many of them going missing in this area. Case in point, I dropped a coin last night into one of my own caches... this morning it is gone and not logged out, no log entry for the cache either... my money says it is never getting logged. I now log every traveler I see. Sometimes I'll move them, sometimes I won't, but it leaves a current record of when/where the traveler was last seen/disappeared so the owner can do whatever they will. I have so far received either silence or thanks/info requests from the owners. Yep, logging "discovers" helps.
I have never attended an event. Stats? Is there a prize or something? Maybe a merit badge or goofy hat? Or is it just for bragging rights? I couldn't help but laugh as I imagined a mob of cachers trying to log a pile of coins/bugs at an event -- and bickering over who had "actually" discovered it first.
Just not my cup-o-tea. I'm in it for the hunt, the creative and evil hides, the adventure of finding new places, the outdoor fun and exercise, and I also log my DNF's cuz, yep, they help too.
Happy Hunting!
