As with most of the Apps, KY does little for the ruffed grouse....deer, turkey and even the elk get the focus now.
I would look for any public/private ground in the east next to Almost Heaven, or the Ohio drainage, the reclaimed mine land not set up specifically for the elk and any early successional that timbering has delivered.
TN, east, mountain early successional.
There are pockets of birds in both states, and Ohio.
Good Luck....your task is daunting and I would watch your impact on a bird in steep decline....grousehunters, despite a decline in numbers, are additive in bad times.
