I'd like to hide some caches in a series. I'll probably have ~ 5-10 caches that are relatively close together, and I'd like to make sure they're all at least 528 feet apart before I submit them, so they aren't rejected.
Is there an easy way to map a series of co-ordinates (perhaps from a list), and add a radius of 528 feet around each one, so I can quickly see if there is any overlap?
