Bobcats like to follow lanes, trails, etc.
Coyotes too, if they can.
Try setting up your camera in those areas if you have access to any.
If you can find a road kill deer, they make a great "attractant" for a camera location.
Be sure to "stake fast" the carcass. You might want to have exactly 24 inches sticking out of the ground. This will make for a good measuring stick.
Who would believe a red fox and a possum would be side by side, sharing a meal?
Find some bobcat sign so you know they are in the area.
Bobcats are sight hunters. Do some research on baiting bobcats and then make a set with an attractor like they would use to trap bobcats. Put it in front of your camera and wait.
Pa_guy mentioned lanes. My buddy has some foodplots along an old tote road. In the past two years he had 4 photos of bobcats walking down the tote road. One of them looks like it was taken by a professional photographer.
