This series of caches was inspired by the excellent Indiana Benchmarking series. I am adding to the Ohio series started by Folboter JAF. The caches highlight benchmarks in Ohio. Each cache will bring you close to a loggable benchmark ... so each find can be a two-fer!
You may find a bookmark list of the Ohio series at
Ohio Benchmark-Friendly Geocaches.
The cache is a nano hidden at the base of the flagpole next to the benchmark. The benchmark is a disk set in the wall of the library about 3 ft above ground level.
