westcliffe01,
I too live in Michigan (near L Michigan), and after carefully tracking down reported sightings of feral hogs, have found the following:
1. most sightings are on old subdivided farms now owned by persons from cities who feed the pretty deer and turkeys (but somehow expect hogs not to eat the feed). These are the same persons who feed the bears, and then are mystified when fluffy the dog goes missing or a person is attacked by a black bear.
2. near the area are farms run by, shall we say less than professional farmers (some of the pig yards are so secure that I would not try to confine domestic turkeys in them).
3. the people complaining to the DNR about damage DO NOT ALLOW HUNTING ON THE PROPERTIES . or lease "QUALITY DEER MANAGED (read:fed and baited) hunts to affluent people from sh*tcago and other locales.
sooo... while there are a few here it is practically impossible to get to them.
rant finished:-{)>
