I realize this is a year old thread but I would like to add some info.
To find the Hinckley range:
Google "Grand Casino Hinckley" on Google maps.
Go East on Hwy 48 two miles.
Select satellite view.
Zoom in to the 500 ft scale.
Find "Mary Ann Rd" on South side of Hwy 48.
Now go back West on Hwy 48 about 1300 ft and see the range on the North side of Hwy 48.
The range is located in the middle of the woods with mostly nothing but woods for a couple of miles to the North.
If you zoom into the 50 ft scale, you can clearly see the block and wood pistol range bench, and the shelter over the benches for the 100 yd rifle range.
The white square near the pistol target area is just a bare cement slab.
The Hinckley Range has a double metal pipe gate chained shut at the entrance.
There is an American and POW flag on a pole by the entrance, as well as a large sign.
There is lots of room to park several vehicles in the grassy area.
The walk around the gate in to the rifle shelter is about 100 yds.
Please clean up after yourself and don't leave garbage on the range.
Far too many slobs do this now

((
In fact, bring a bag and take some extra with you when you leave

If there are squad cars sitting out front and the gate is open, come back another day.
The Pine Co deputies are doing a qualifying shoot.
