Cache Density Distance (File=>Export=>HTML)
The HTML "cache density" summary will show you the top 50 caches in descending order of density of nearby caches (using your current centre point). You set the distance for this calculation here. This is a good way to pick a cache to start from when doing a "cache raid"
Note: Just setting the distance is not enough to get the summary - You must make sure you also check the "cache density" box in the Indices to generate.
