As of today, there are 16 'member-only' geocaches in SLAGA territory. What is 'member-only'? This is a desigation set on a cache by the cache owner, allowed by geocaching.com. If you don't pay your annual dues to become of Premium Member of geocaching.com, you won't see any 'member-only' caches when you do a search by zip code. Keep in mind that is is NOT a restriction that has anything to do with SLAGA and is not tied to annual SLAGA membership dues. Here is the geocaching.com explanation: Member Only Caches Some caches are only available to Premium Members. This has been a request of many geocachers who want to put more energy into designing a cache for dedicated geocachers. As the cache owner, you can make any of your caches "subscriber only" so folks will need a subscription to seek it out. (Note: Member Only caches may not be any better than public geocaches. Each cache is managed by its cache owner.) What is SLAGA Territory? An arbitrary designation set years ago that encompasses a scope of caches around the St. Louis area where most of the SLAGA membership does their cache hiding and hunting.
