This user earned the Ninja geohash achievement by completing the whole expedition in under one hour while visiting the (54, 13) geohash on 2018-11-28.

Definition

• You get the ribbon by completing the whole expedition in under one hour. Like a Ninja, no one even realized you were on the hashpoint.
• By expedition it is not meant only reaching the geohash, but the whole trip also back home: Home -> Hash -> Home. Or if you find the hash in your way to work the expedition would be: Home -> Hash -> Work (or backwards). Or if you have other plans, like meeting someone, but on you way you can find the hash: Home -> Hash -> Meeting point.
• Time difference from starting time and finishing time must be under one hour.
• Proof would be starting and finishing times of the expedition. Photos of times, or GPS track could be helpful proving it.
