This is probably the only "Well rounded" challenge that I will qualify for - the Silver and Gold seem to be heavily weighted towards people who find mostly trads. Surely to be well-rounded you should find different types of caches (why should it matter how many trads you find).
I qualify with
3362 caches (500 required)
562 Traditional caches (400 required)
212 Multi caches (50 required)
2122 Mystery caches (20 required)
54 Earth caches (5 required)
163 Letterbox caches (5 required)
13 Wherigo caches (2 required)
100 Event caches (5 required)
23 CITOs (2 required)
This one took me quite a while to find. Initially I was on the wrong side of the fence. I spent ten minutes there and then finally realised my error. On my second go I found the footpath and was soon searching in the proper place. I finally found it in the third set of roots I tried after another ten minutes - the cache was smaller than I was expecting.
