This being a sports forum, I though maybe someone would find this useful. National Geographic just put these up on their website. It's got an interactive map, and then formats each for standard size paper. Kinda cool, considering how much they cost at a sports store.... Personally, I prefer these over relying on my phone, if I'm out in the hills. Anyways.... http://www.natgeomaps.com/trail-maps/pdf-quads
So being that National Geographic is now owned by that Rupert Murdock. I take it a server automatically downloads media that links you to ISIS while reporters show up at your door. (He he. Just kidding. Thanks for the link.)
