Play with the coordinate calculator here: http://xkcd.com/geohashing

Every day, the algorithm generates a new set of coordinates for every
region. They are randomly placed -- they could be in the forest, in a city,
or on a mountain.

Unless you can predict the stock market, you can't figure out what the
coordinates will be ahead of time. You can first calculate a weekday's
coordinates at about 9:30 AM (Eastern), and on Friday morning you can
calculate the coordinates for each day that weekend.

PS. For those of you who don't know, XKCD is a web comic of sarcasm,
romance, math, and language. I suspect that GPSes fall into the math
category.
