We have been caching for a while and hope to reach our 100th find by the end of the year. So we were wondering, what are the significant cache find levels? What should we be celebrating: 100, 250, 500, 1000, 2000, 3000? I've seen special geocoins for different levels and other paraphernalia. I know all caches are special , but what are the core, always celebrate, "you have achieved greatness" find cache find levels?
