This category is for expeditions that are not geohashes. They are not to the daily coordinates, nor are they retrohashes, nor designated alternates. Such an expedition typically consists of one or more geohasher going somewhere and doing something for a reason somewhat inspired by geohashing, perhaps using an alternate algorithm or experimenting with a new vehicle.
While it is in no way the place of the geohashing wiki to discourage any type of expedition, reports of such expeditions are discouraged on the wiki because they aren't geohashing and could cause confusion. When our discouragement is insufficient and such a report is made anyway, it should not be named or categorized as if it were a real geohashing expedition. Category-obsessed wikizens may place it in this category.
