I used to hunt a place with a large levee running through it, If they did work on the levee and planted grass those new tender seedlings were like money in the bank. I've seen them go nuts over persimmons in places and totally ignore them in others, I've seen them eat the seeds that fall from cypress trees, honeysuckle is really good in the late season especially if there is snow or ice, white oaks and pin oaks are usually good all fall. Agricultural fields are our number one food source. but in the larger timbered areas I hunt without them I'm going to be looking for big white oaks with the most sign under them most of the time.
