I take this to mean that that run was placed with the full knowledge that they would be there only a limited time. What happened to the permanence clause in the guidelines? Would that not have made these sanctioned temporary caches? Isn't that (placing temporary caches) a no-no? I seem to recall a huge dust-up a few years ago about temporary and pocket caches.
To quote the guidelines:
If these were, indeed, placed with the knowledge that they would only be there a short time, then it would seem you have another naughty item to add to your list.
You are assuming (incorrectly) that humboldt flier placed the caches on the TOG
