Is there a checker already in place for all of the 'Distance to Find' categories? In miles, there are twelve "<1 mi, 1 mi to 10 mi, ...5000 mi to 7500 mi and > 7500 mi". I was thinking of doing a challenge (when we are allowed to again) that you'd have to have at least one cache in each of the distance categories (either mil or km) and would like to include a PGC checker if one were available.
