So, how do I arrange to get an area like this?

Ah, Grasshopper... to achieve such a worthy feat requires the rare combination of stealth, persistence, and thinking outside the box (but just barely outside it).

And where do I get those statistics for an area that I want to test?

Roughly how many boxes are there at Stone Mountain, and how big is the area?

Stone Mountain Park is 3,200 sq acres, about 3,000 of which are accessible. There are currently atleast a hundred active boxes (boxes I have physically touched since 6/18) plus another 250 or so I'm still trying to figure out or in parts of the part that I'm saving for group boxing trips, or that have just confounded me. I'm pretty sure stone mountains claim to highest density was more true ten years ago than it is today- but the density is high enough that I found a handful of boxes before I ever read a single clue...in some parts of the park it's like every 100 yards there is or once was a box.
