I use corn and what i do is take 100lbs and spread it out over a 10-15yd area about 10 days before the season and go back in 5 days and spread 50lbs if it is gone. Then when the season starts if you carry 15-20lbs in with you every time you hunt that stand you will always have corn on the ground.You have to spread it out, if you dont when it is gone they will be gone spreading it out allows them to have to search for it which makes it last longer .and you can have more deer in that area, if it is a single pile they wont come in if1-2 deer arealready on the pile. Good LuckP.S. don't use cracked corn or you will have so many birds on the corn it will keep the deer away.
