Well, it is not the amount of caches (2500) I am most disappointed with, but the thinking in circles, or rather radius range from a point. It would be much easier to be able to get slices of longitude and latitude within a country or state. In this way you could be assured that you get all caches in an area and no duplicates. If you for instance are driving close to big cities, you get too much caches with the circular approach!
