Geohash on a slow Sunday

The latest thing in this household is a new activity, geohashing.* Basically, geohashing is being told where to go in the belief of patient fun and maybe meeting someone, all at random.

It works like this:

(1) Get ready to go -- sandwiches, friends, camera (especially);
(2) Find your part of the world (graticule) on the site's interactive map;
(3) Enter today's date and find out where to go. The randomness comes from an algorithm hashing the Dow Jones Industrial Average is published with the date to create coordinates for every graticule in the world;
(4) Try to get to the geohash point for 1600 hours. GPS and rulers help. Then, either (i) rejoice in your success, (ii) rejoice in your failure. In both cases, have fun and take some interesting pictures of wherever you have ended up.

If you want, you can post a report of your expedition when you get home.

We met no one new, indeed no one at all. But for a random set of coordinates, we stopped at quite an acceptable point of a sandy beach and chuckled to ourselves.

I really do have lots of things to occupy myself with: books, spinning, gardening, blogging. But today's expedition is just what a slow Sunday should be.

*Geohashing originates from the wkcd web comic. 503 is rather poignant to the geohasher per se, and 162 suitably cross-matches with my slow mood.
