 A Tale of Two Hashes Challenge
Grüß dich! I've been waiting a long time for this one! Today's -37, 145 hash (East Melbourne) fell in Heidelberg - right next to the Heidelberg Train Station! This should be pretty easy for one of you to match up with a hash in your beautiful city. Good luck!

- Thank you! I've been hoping for somebody to post that challenge, considering how many Heidelbergs are out there all over the world. It would be extra cool if the next hashpoint in Heidelberg lies next to Heidelberg station, too. ;) --ilpadre 04:17, 18 December 2011 (EST)

I'll be at Heidelberg on 2012-01-15 and probably will go there a bit earlier. Unlike last year, I definitely can't really make any plans in advance yet. It might be a visit for a few days just as well as it might happen that it's being cut down to a daytrip (in which case hashing would be quite unlikely). If anyone around is interested in a meetup on e.g. saturday 2012-01-14, I'll see what is possible. --Ekorren 04:06, 5 January 2012 (EST)
Thomcat will be traveling from Frankfurt to Nürnberg on Sunday, and is considering the Mannheim geohash for this day (near a shopping center). Interested? Reply on my talk page. --Thomcat (talk) 11:07, 21 February 2014 (EST)
- IMHO it's not really an achievement to not meet people you could have met. But you can always create your own Gratuitous ribbon. --Ekorren (talk) 07:02, 15 May 2014 (EDT)

I'll be at Heidelberg a few days. If someone around there plans to go hashing (public transport or walk geohashes only), I might consider to join. Saturday and monday all day, friday evening, sunday possibly spontaneous if close. --Ekorren (talk) 03:33, 8 January 2015 (EST)
- The only (halfway) realistic aim would be 2015-01-11 in Angelbachtal. It's an hour by public transport from HD and I could go there by bull. Just tell me if you're interested (and able to come), and I'll see if the weather allows the ride.DODO (talk)

Both OSM and Google maps place the railway tunnel "Neuer Schlossbergtunnel" between Heidelberg Hbf and Heidelberg-Altstadt almost exactly under the hash. This means that people could score the rare Going deep geohash achievement as well as the proposed Over and under achievement and possibly the Stacking achievement. Anyone interested in these? --Ekorren (talk) 18:50, 30 January 2015 (EST)
