I have a different perspective. My favorite caches are traditional ammo boxes in the woods and regular size caches in general. I find more of these than any other size and try to keep them at more than 30% of my total finds. Because I like to encourage children who are caching, I carry hot wheels cars in my geobag and add them to caches I find if there is room. I also carry spare logs of various sizes, extra pens, etc. to make the finds better for those who follow. I write moderately long logs to express my appreciation for the cache owner's work. Twice I have refreshed a neglected cache.
The first, Lizard Lane GC2R7WG, was a few miles from my home, a rare regular size trad in this urban setting that had been in a tennis ball container. Its physical decline was well documented in the logs followed by DNFs. The CO had not been active in geocaching for a number of years. I prepared a regular size cache in a 2 lb nut jar with swag, log, pens, cars, and a TB and hid it in the original spot. It has been found by 51 cachers since I first refreshed it, many of them just getting started. I particularly treasure the photos of two groups of young children who loved the cache. I keep a watch on the cache and refreshed it again when it was muggled.
The second, Denton, Former Maryland MML Geotrail GC41191, was one I wanted to find on a trip I was making to this area. The previous owner posted that the cache container was removed temporarily on 3/31/14. A new owner logged accepting responsibility for the cache on 4/01/2014, but there were only DNFs after that. A recent log made it clear that the searcher should have found the cache but it was missing. I visited on 5/29 and left this in the log:
"This could have been a DNF, but like the cacher before me, I was confident I had found the hiding place but the box was missing. I placed a temporary cache including a pen, a log book, a hot wheels car, and a TB so that others will be able to find the cache until the original box is returned or replaced. I am sending a photo of the hiding place to the cache owner to confirm that the location is correct."
Five cachers logged my temporary cache replacement, mostly travelers who had come to the heart of this little town to find the cache. Finally, on 6/26 she had someone else replace the cache for her. She emailed me that she didn't appreciate having her caches replaced because they were usually hidden wrong, and I sent my photos showing the correct spot. She also deleted the DNF logs. I didn't reply, but I don't appreciate a CO who has so little regard for cachers. If a cache of mine should go missing, I'd appreciate someone who gave it a temporary replacement until I could get back to it.
Throwdown is a derogatory term and doesn't apply to every cache replacement.
