A good quality geocache is one that is airtight and watertight such as a top of the line Lock & Lock , or the favored ammo can. It is even good quality if it's in a small pill bottle wrapped in a baggie. Anything that you open up and you don't see mold mildew and water is good quality. If Groundspeak is looking to improve the quality of geocaches out there , a CO rating system can be developed such as in what eBay asks you to do. Rate the seller, rate the CO. Coordinates should be good and a decent hint should be provided in remote areas especially. just a thought. Co's are supposed to do maintenance, so if your geocache was once high quality and irresponsible geocachers or muggles turned it into poor quality, then the CO must get out there to make it high quality again.
