Odds are you already have a pretty good idea of which food plots and fields are most likely to attract winter deer, but you need to verify it. Winter deer key in on certain food sources for a variety of reasons, including proximity to bedding, snow depth, exposure to humans, and more. The only way to know for sure which ones the deer are using now is to go check for sign. By the way, keep an eye out for sheds as you scout, as some bucks can drop early. If you have wireless cams in your arsenal, place them on the most difficult plots to access (for you) or the ones that you know are close to bedding/security cover, so that you’re not repeatedly bumping the deer you want pics of.
