Reverse regional achievement
This is the opposite of the Regional Geohash Achievement: Instead of visiting hashpoints in every graticule in a given region, the goal is to visit hashpoints in every region in a given graticule. For example, the Boston, Massachusetts graticule (42 -71) spans 4 US states, so to gain this achievement it would be necessary to visit hashpoints in that graticule falling in Massachusetts, New Hampshire, Connecticut and Rhode Island. You are free to increase the difficulty of the reverse regional achievement by aiming for smaller administrative divisions, e.g., in a graticule spanning two countries, you can go for hashpoints in both countries to get the most basic reverse regional achievement possible, but you could also try to reach coordinates in all respective subdivisions of both countries (states/provinces, then counties to make it even more difficult, etc.).
The graticule should span at least two regions, else it's just too easy.
Alternate meetup locations do not count for this achievement.
