I have just become aware of a cacher who logged 330 Virtual caches in one day. Strange thing is these caches were in the states of Arizona, Utah, Colorado, Wyoming, Nevada, Idaho, California, and New Mexico. The cacher may claim he found those caches over a period of days and just logged them all on one day, but on previous and subsequent days he logged other caches. I have found several of those virtual caches. One that I recently found takes a whole day to drive to and back and an hour to hike to the cache (Savanic Mine). There are many other caches he claimed that are just as difficult to get to. In my estimation it would take a least a month to drive to those 330 caches, hike to the locations where needed, and find the information needed to log the caches. His log on all of the caches was the same. I know that some cachers in Arizona are upset about these logs (see Photograph Arizona). In the past, when such wholesale bogus logs are discovered and GS is contacted, they have been reluctant to do anything about it.
In the west many cachers participate in the Lonely Cache Project. Caches accrue points based on how infrequently they are found. Bogus logs can cut the point values of these caches in half. Bogus logs can ruin this fun geocaching game alternate. I know cache owners can delete bogus logs, but I have found that often they don't, even when contacted. I would hope that premium members would be upset enough about bogus logs to push GS to do more about it.
