It all depends on whats available where you hunt. Like my farm for example we had winter wheat this spring and summer and due to the lack of rain the farmers didnt plant beans. So we had dirt. Fortunately our food plots werent a complete disaster so we hunt over those a fair amount with success. The neiboring farms have both corn and beens, although we cant hunt over those fields we can catch the deer coming back to bed on our ground. Id say usualy they key in on corn more in the winter but everywhere is different. Never stop scouting, keep your options open and hunt hard.
