The cache is NOT at the posted coordinated. It will be a great place to park and walk from there. 

M-66 is a north–south state trunkline highway on the Lower Peninsula. It runs from the Indiana state line in the south to Charlevoix in the north. M-66 is the only state highway to run the north–south distance of the Lower Peninsula.  The total length is approximately 272.9 miles, which includes almost 3.4 miles of freeway between Interstate 94 and downtown Battle Creek. Otherwise M-66 is a two-lane rural highway.

The first usage of the M-66 designation dates back to around July 1, 1919 with the rest of the original state highway system. At the time, the highway only extended between Lowell and Lakeview, a route now covered by M-91. The highway has been lengthened in a series of extensions north and south starting in 1925. A rerouting in 1944–45 removed M-66 from its original 1919 routing to replace another highway south of Six Lakes, the change that spawned M-91. The last big extension in 1965 resulted in the modern trans-peninsular highway route. The last modifications were shorter reroutings in the 1970s.
