The cache is NOT at the posted coordinated. It will be a great place to park and walk from there. If the gate is shut/locked there is room to park in front of the gate and you may walk from there.

M-91 is a largely north–south state trunkline highway in the Lower Peninsula. It runs from Belding to south of Lakeview. Its 24-mile length exists entirely within Ionia and Montcalm counties.
M-91 was formed when M-66 was rerouted in the 1940s. At the time, the highway continued south to Lowell, but subsequent transfers or roadway sections have truncated the route to its present form. For a time period in the 1980s, M-91 was even a discontinuous highway when a section in the middle was transferred to county control before the southernmost section was transferred.
This is a challenge cache where you must meet the requirements before claiming a find. I am fine with you signing the log and then posting the find after you have completed the challenge.
The Challenge is to find 91 caches in each of the counties M-91 passes through. Listed below:
Montcalm
Ionia
