Challenge Cache: A type of cache where you not only have to sign the log, but also complete a challenge. This cache is located at the posted coordinates.
This Challenge: You must have found a cache in a total of 1000 grid squares in Ohio. You can count up to 81 squares for EACH Ohio County of the 88 Counties. Each DT grid square to contribute to this total must have at least one cache found.
Specifications: For example,
- if you've found at least one cache in all 81 DT grid squares for caches in Franklin County, that counts as 81 squares toward your total
- if you've found at least one cache in 30 grid squares for caches in Licking County, that counts as 30 more squares toward your total
- if you've found no caches in Cuyahoga County, that means you have to cache more in Cuyahoga County, and your total is not increased at all.
- if you've got 2 DT fizzy grids in Hamilton County (2 caches in each of the 81 grid squares), this counts as 81 squares toward your total (not 81x2)
