[microtonal]

A lot of seriously dedicated "off-the-beaten-track" types will have solar chargers for their iPhones (or whatever), GPS works everywhere except near US Military Bases.

Or just switch their phones off, unless they need help, if you are lucky enough to have reception. The "off-the-beaten-track" types that I know use paper maps, or a Garmin GPS that lasts two days while continually using maps on two AA batteries, that can handle occasional drops and water.

I like hiking every now and then, but do not really see use for this. What does it give me over uploading my tracks on the many 'show my last hike track' websites?

Besides that, I can really see this being harmful for nature, people destroying vulnerable plants and animals just to remove a particular piece of fog. It's as sad as people completely 'flattening' a some spot to find a particular Geocache.

(I do like responsible Geocaching, but people should be made aware of damage that they could make.)
