This cache is near the Vonore Public Bike Trail. (It's basically a road that's blocked off to auto traffic). There is a gate that blocks the road, and you can't park next to the gate. But, there is plenty of shoulder a hundred yards back from the gate. It's a dead end road in an industrial park, so occasional truck traffic but only busy at shift change.
You will have to walk about 1km on a paved road and then do a few hundred yards of woods thrashing. However, it will likely be easier if you have a boat.
Gratz to Millasmommies12 on FTF!! Hope you got the rare and desirable Sacagewea dollar coin :)
