Each of our caches is placed for a reason: scenic spot, historical significance, interesting geography/construction. None of them was placed at a stop sign or guardrail "just because". They're traditional caches with swag, real log books, and are big enough to place most travel bugs. And we maintain our caches.
Yes, we could put out more caches, and we intend to one of these days. But we prefer quality over quantity.
You could also argue that geocachers should give back by sponsoring a geocaching event once in a while. You could probably count on your fingers how many GCM.org cachers have sponsored events. Well - at least on fingers and toes both. Which makes about 20 people - less than 1 percent of GCM.org members.
