Walk Geohash
Earn this award for walking all the way to a geohash from your usual geohash starting point, typically your home or office. It's definitely against the spirit of this achievement to stay over Friday night at your friend's house, or drive over to do some work at a satellite office in order to start within closer walking distance of the geohash. Driving your car to the base of a mountain containing the geohash and walking all the way up does not count, even if you have to walk forty miles. You have to proceed the entire way on foot.
Running, climbing, scrambling, crawling and taking turns carrying other geohashers in your party on piggyback still count as walking, and swimming across a body of water to reach the geohash does not invalidate your walk. You must not bicycle, skateboard, kayak, take public transit, or accept a lift other than a piggyback ride on a walking person. Snowshoeing or sliding down a snow-covered slope on an improvised sled do not invalidate the walking achievement, but you may not take the Walk Achievement and the MacGyver Achievement for the same expedition. Either it was a vehicle or it wasn't. Travel wholly or partly by crutches or wheelchair qualifies for this achievement.
Remember, there's no such thing as "not within walking distance." It's just that some walks are longer than others, and if you're not good at walking underwater, sometimes you have to wait for winter freeze up, or a major geologic event in order to proceed in your desired direction. (Note that underwater walking does not qualify you for the Underwater Geohash achievement unless the geohash is reached while you are underwater).
