In the middle and late 80’s i would see 6 or 8 per day while running my bear baits. A week didn’t go by that ai didn’t have to pull quills from my hounds.
Then they disappeared and i didn’t see one for 20 years—except for when IO was in Minnesota and Wisconsin.
Now the they seem to be making a comeback—saw a couple of roadkills last year and have seen about 6 this year.
