Plans

Attempting a public transport tron geohash, which, to my knowledge, has never been done before. I've wanted to do that since the day the achievement was created, seeing as being bound to a few possible routes makes this the most challenging form of tron geohashing. I've planned several tron-train geohashes before, but this is the first one that might actually work.

The plan, here's a map for those who want to follow [1]

• Leave house to the north, walk to the tram stop Sinsheimer Straße, take S2 to Hagsfeld Bahnhof (not on the map, since the map only includes buses)
• Take bus 31 (the red line on the right part of the map) to Durlach Friedhof, here's the exact route [2]
• Walk from Friedhof the the stop Durlach Turmberg. The 31 actually goes there, but uses the same road as bus 23, which I'm going to take, for a few meters, which would invalidate the tron geohash. As I have 18 minutes waiting time at Turmberg anyway, this won't cost me any additional time.
• Take bus 23 from Durlach Turmberg to Stupferich Pfefferacker, map [3]
• Walk from there to the hashpoint, which is in a field, enter the field from the north, leave to the south, continue walking to the stop Stupferich Auf der Römerstraße.
• Take bus 47, map [4], back to Zündhütle, from there take tram 2 and tram 4/S2 back home, enter house from the south.

All buses involved go every 20 minutes during the day, trams every 10, so timing isn't an really an issue. I plan to leave my home at about 8:00, arriving at Stumpferich at 8:56.

• Weather update: After lot's of snow and temperatures of -10°C over the weekend, it's now around 1°C and raining like hell. So inb4 drowned rat geohash and muddy shoes (again). Leaving in 30 minutes. 06:16, 22 December 2009 (UTC)

Report

Everything went better than expected. Five minutes after I left my house, the rain stopped. All bus connections worked, too, public transport tron geohash is done. Field was muddy, but I was prepared, wearing more water- and mudproof shoes this time. Most field paths were covered with a layer of ice, yet the temperature was probably above 0°C, so no Frozen geohash. Coordinates were reached at 9:15, snowman was built.

Also, I was trying to create a live broadcast from the hashpoint via ustream's iphone application, the network coverage wasn't good enough though, so I took a short video and uploaded it at home. And here it is.

Koepfel earned the Tron achievement by reaching and returning from the (48, 8) geohash without crossing his own tracks on 2009-12-22.

More to come.
