How do you discover the world around you, using your Android?

According to the revised edition of Bethy Mac's Rules of the Universe, use of a smartphone while hiking is only permissible if 1) the user is looking up information which will then be read aloud to the group, or 2) the user is experiencing an emergency. With that in mind, it is interesting to note that cell phone service is available through a surprising amount of the Great Smoky Mountains National Park.

Google Maps' Android app can display Wikipedia articles about points of interest in your locale. To activate this feature, open Google Maps, touch Menu > Layers, then check Wikipedia. W icons point to Wikipedia articles pertaining to points on the currently-displayed screen. Touching an icon displays the name of the article, linking to a short version of the article within the Google Maps app, with the option to open the full article in your browser.

To avoid confusion, we will review acceptable as well as unacceptable incorporation of Androids into group activities.

The Mount LeConte trailhead, in the Great Smoky Mountains National Park, where seven inquisitive hikers are reading information signs and debating the pursuance of this trail. 
Acceptable
HIKER 1: Weren't they talking about this one at the visitors' center?
HIKER 2: Yeah, I heard it's popular. Must be pretty easy, if lots of people like this one.
HIKER 3: Let's check, just to be sure we know what we're getting ourselves into.
HIKER 2: I guess if you want to kill the mystery of it all.
HIKER 3: I do.
(HIKER 3 opens Google Maps, which shows their current location. The Wikipedia article "Mount Le Conte" is located immediately, and HIKER 3 begins to read.)
HIKER 3: "Third highest peak in the national park, behind Clingmans Dome and Mount Guyot... from its immediate base to its highest peak, Mount Le Conte is the tallest mount in Tennessee, rising 5,301 feet..." 
HIKER 4: Well, that sounds like an all-day hike, and I plan to be hungry within a few hours.
HIKER 1: Let's go to Clingmans Dome, where that thing is.
HIKERS 2-7: Sounds good!
Unacceptable
HIKER 1: Weren't they talking about this one at the visitors' center?
HIKER 2: Yeah, I heard it's popular. Must be pretty easy, if lots of people like this one.
HIKER 3: I'll look it up.
HIKER 2: I guess if you want to kill the mystery of it all.
(HIKER 3 is already in Phoneland, opening Google Maps, which shows their current location. The Wikipedia article "Mount Le Conte" is located immediately, and HIKER 3 stares at phone in silence.)
HIKER 3: Looks intense.
HIKER 4: Ok, let's save that for another day. What else should we try?
(HIKER 3, staring at phone, snorts.)
HIKER 5: Did you find something?
HIKER 3: (Sniggering) I just followed some links to other articles, and it turns out some people actually think pigs can fly!
(HIKERS 1, 2, 4, 5, 6, & 7 wish HIKER 3 would stay on-topic.)

Wrapping up our life-application session, keep in mind Google Maps' Wikipedia feature for use as you tour new areas. For example, if you were vacationing by bouncing around the Big Apple, you might pass the Radio City Music Hall, where the Samsung Galaxy S IV was unveiled last evening (as speculated, it is too similar to the Samsung Galaxy S III to be exciting). Perusal of the Google Maps' Wikipedia information reveals that Showplace of the Nation is this famous landmark's nickname. Obviously information like this will enhance the excitement of your vacation incalculably.
