Seed caches

For some time there have been caches called seed caches that contain lots of small cache containers -- usually 35mm film canisters -- with instructions that geocachers who find the "spawn" or "mother" cache should take one of the seed caches and hide it "to keep the game of geocaching going." However, Groundspeak has instructed reviewers that seed caches constitute an ALR (additional listing requirement) and therefore reviewers should not publish caches that require or even encourage people to hide "spawn" caches. I think this is a good idea because too often, the seed caches obtained from mother caches were placed in less than ideal locations with little thought going into them and little maintenance provided after the hide.
