So we were out for our second geocaching experience. We found a pathtags "coin". We logged it in, there was not a note about passing it on, so that means we "can" keep it, though I think it would be fun to keep it going. Anyway, we left a little toy swag for it. My question is what is the appropriate protocol--should we have just left the coin if we didn't have another coin to leave? Is there a rule that we didn't know?
thanks!
