Location

In the schoolyard of the Friedrichschule, an elementary school in Plankstadt

• Koepfel

Plans

Next to a school in Plankstadt, insanely close to the 2010-07-28 coordinates. While I back then couldn't go due to time constraints, I will probably try to walk to the hashpoint on Monday. Unfortunately, no Juggernaut, since 6.2 km (straight line) and a deviation of about 500 m => 5:62 > 1:20, although I will be able to travel most of the way in a perfectly straight line.

Might try it as well. I'd try to go sometime in the late afternoon (maybe 17:00) Koepfel _talk 19:17, 31 July 2010 (UTC)

Expedition Report

Ilpadre

Tracklog: http://www.everytrail.com/view_trip.php?trip_id=734463

I didn't want to miss a hashpoint in walking distance, now that I finally have time to go on expeditions again. Expedition went just as planned, even the walking didn't hurt as much as I had expected after more than a month without training. Just the occasional rain was a bit annoying.

  Found the coordinates.

• 

  Left a marker for koepfel.

  Obligatory.

  Walked a different way back, mostly through fields.

Koepfel

Took a train from Karlsruhe to Schwetzingen, walked to the hashpoint by 17:00, found Ilpadre's marker, a couple of small stones spelling "xkcd".

Left at 17:15, walked to Eppelheim, revisited 2009-05-21 49 8, walked to Pfaffengrund and took the tram to Heidelberg.

  Revisiting 2009-05-21 49 8

Koepfel earned the Consecutive geohash achievement by reaching 4 consecutive hash points starting on 2010-07-30.

Accidental Juggernaut

Even though took over half a year to upload the image to the wiki in January 2011, I downloaded them to my computer right after the expedition. And while doing that, I saw that Ilpadre originally intended to do a Juggernaut geohash. I also noticed that the train from Karlsruhe to Schwetzingen I took runs along a surprisingly staight line. So I tried to find the maximum deviation from the straight line and drew this map. The maximum deviation I found was when the train ran though Waghäusel, 2.05 kilometers. With the direct path being 42.9 kilometers, it's 2.05/42.9 = 0.048 < 0.05 = 1/20.

Koepfel earned the Juggernaut achievement by reaching a geohash in a straight line (with a deviation of 4.8%) on 2010-08-02.
