Calling a buck in still isn't going to work worth a darn, but if you're determined to give a try, stick with just some light tickling of your rattle bag or handheld rack. Bottom line is, for right now in most places, you still want to hunt the food. I was amazed to see bucks and does feeding voraciously on turnips, ripping them from the ground, despite their being more of a late season food. However, when brassicas were planted next to clover, the deer would feed briefly through the typically winter food and hang out in the clover. The lesson there, if you have numerous plantings on your property or lease, focus on the clover or other warm weather foods deer prefer.
