I have personally seen some damage to lawns near Midland, and I have seen the tracks where they cross roads, and where they forage in the ditches.
(some deep ditches in the Midland area). Deer avoid going into the deep wet ditches, pigs head there to feed.
I tried and tried to get permission from the nearby landowners, to no avail. These people want to keep the pigs to themselves, because I have heard there are a good number of them being killed during firearms season.
I have seen photo`s of two boars killed with shotguns, and they were dark, and hairy. The ones I saw in the photo`s looked like Russian`s.
The pigs are almost totally nocturnal, and when they turn up a lawn, the residents go to bed with a nice lawn and wake up with patch of worked up earth.
Much of the land in the areas just north of Midland is low and wet. Lots of tight brush close to the ground. Perfect for pigs.
Baiting for deer is still widespread in the area, and the pigs feed freely during the night.
The last batch of tracks I saw there in late October contained tracks of all sizes, and we all know what that means.
I personally searched the areas said to have hogs in Ogemaw county, and never found any sign.
The areas near Midland that I spoke of are just a little east of Meridian Rd (M-30) and just north of US-10.
I saw pig sign just south of the little town of Hope, and just a little further south.
If you go looking, you will see the kind of brush I describe when you are in the right spots.
I found that most homeowners do not own adjacent land, and own only enough room for a house.
Good luck...they ARE there.
