If you can find an out of the way oats field thats is a good place to look for sign. Beards will knock down and destroy much more oats then they eat but the sign should be obvious if they're in the area. Abandoned apple orchards are also good places to look for sign.

Bears don't have very good vision but they have excellent noses and hearing. If you find bear sign hunting the wind is of utmost importance. You're best bet if from an evevated stand overlooking a fall food sorce. Scent control is as important as stand location. Find the food, sit quitely and pay attention to the wind(your sent).
