Well - it´s me... but who am I ? I am not sure whether i am sure.
I started visiting xkcd.com regularly some years ago for the comics, and began geocaching somewhen in 2009. Since at the moment geohashing is a quite often appearing subject in several geocaching-blogs, I had a look at the idea and found out, that today (at 2012-02-25) the coordinate in my graticule is quite close to my home coordinates, so i thought i´d have a try.
I am not sure about how often this will happen again ;)
I am sure that if it will happen again i won´t be as silly again to forget the memory card of my camera at home ;)
