I definitely understand not wanting to pay for more than one premium membership. My son will soon be old enough to start finding caches and I probably won't get him a membership. Is there anyway for a CO to allow them to log it without a premium membership? Once you have the cache created can you go back in and uncheck the premium only box for a little while so they could log it? It wouldn't be ideal unless you knew the CO but if it was me I wouldn't mind doing it. Just a thought.
