We just became members and have not made any plans to do MOC mainly because there are so few caches within a 50 to 60 mile radius of our home. We subscribed because we enjoy the sport. One criteria we use when placing a cache is the difficulty in getting to and finding the cache. The tougher it is the better the items in the cache. We also ask on the cache page that people trade equitably so others will be able to find something nice. When we hide a cache it is for our enjoyment first, then for the enjoyment of other cachers second!!! If no one finds the cache we still had the fun of Geocaching. That is why we subscribed.
