What baiting I do I carry in.
That said, I know some guys who use feeders & as long as theyre flled regularly so the deer keep coming I'v been told they are often in earshot when the feeder comes on & when they hear it they come in. believe this as have a friend who feeds deer (Doesnt hunt tho) off his deck from a 5 gallon bucket. He empties out a bucket of corn & bangs it on the railing to get out the last bits & the deer come out wthin minutes of his banging the bucket.
