Might try state parks in Latimer, Le Flore, McCurtain and Pushmataha counties. These are all in Southeast Oklahoma and are the 4 counties in Oklahoma that have a good bear population. Contact the game wardens in those areas as well. They might be able to point you in the right direction.
Good suggestion. Nuisance bears will be hanging around the parks.
Btw my wife is a budding photographer as well. She got some pics of 2 bucks fighting behind the house today. I'll get them posted.
