 Interesting Hashpoints
- Neil wonders if 2010-09-13_52_1 is in a tiger enclosure. The hashpoint is at Banham Zoo.
- Stealth hashing is fun but not today! Is there a get yourself arrested award?
- 2011-01-17 52 0 - A nudist beach hashpoint. Sadly it was a freezing January night.

Have all the geohashers been "Nerd Sniped"?
My user name is a play on words based on computer source-code and is a tribute to controlled folly.
I enjoy computer programming and in 1972, wrote an implementation of Conway's Game of Life in BASIC. The virtual creatures were printed on a paper roll by a mechanical teletype. Those were the days!
In 1976 I taught programming to school kids. We used Algol! We filled in coding forms and submitted them to be punched onto cards for the overnight run. The next day we'd get the error message print-outs or occasionally a successful run.
One of my follies is to go geohashing with an emerging penchant for stealth hashes, unobserved, often at night. If possible, to save fuel and the planet, I visit pairs of hashpoints each side of midnight. This is great for wildlife spotting and the roads are empty. Like golf and most other human activities, geohashing is totally
pointless (in fact it is one of the few activities that has got an identifiable point) and it's much more fun than geocaching or golf. Many hashpoints are in the middle of a muddy field. These are a bit worthless but if there's some other attraction or challenge, I'm more likely to make the effort. In 2015 Sourcerer discovered a previously unsuspected competitive streak leading to a serious increase in geohashing activity. For some grand scale folly, see Neil's Big Walk below.
The NWoodruff map expedition numbers disagreed with mine. I tracked the problem down to my own mis-recording. I had counted a "not attempted" as a "coordinates not reached". So I have spent half a day correcting my numbering. It's like re-buttoning a coat except 100 buttons were out of sync. I now have a double century (minus one) ribbon!
 Local Terrain
The terrain in the east of England is almost flat and often quite dry. Google earth has been most useful for planning expeditions. Usually it's easy to identify hashpoints which are on private land or inaccessible for other reasons. After 100 expeditions, my success rate was 86%. In late August and autumn, most of the fields have been harvested but not yet re-planted so they are easily accessible. In the other seasons, it's often wetter and access is less easy. Hard frozen ground in deep winter is really good for geohashing.
 Big Walk
Another folly is to walk from Cape St Vincent (Portugal) to Istanbul (Turkey). Starting in 2003, after 183 days walking and 3798 km, Neil had reached Vicenza in the north of Italy. The walk is about 50% complete. Neil is not seriously expecting to complete this walk but that is all part of the folly. He set out with his mother and sister. Both have since died. His mum reached a ripe old age. His sister died of cancer but she walked 2567 km before the cancer overcame her. She reached France. Geohashing is a good way to keep fit enough to continue with the big-walk stages.
This is what Google Earth looks like if you download the KML file. It makes more sense when you zoom in.
