I always say "follow the feed." Whitetails are kinda off my radar, but I know they are easy to pattern until the rut. Watch where they feed and they will be there right before sunset.
Mule deer are less predictable and are different in different areas. I just got back from Kansas. Those bucks are in milo and corn right now. Far different than the Grey's River bucks we chase here in Wyoming.
I've noticed the deer in our sagebrush/mahogany country here in Wyoming are often up higher on ridges until the feed there dries out (and the higher waters also dry up). They'll eat forbs mostly until the green is gone. Then they move to the good summer brush, which is generally mahogany. Then in the fall after the mahogany leaves fall off, they transition to bitterbrush if they can. Then after it gets cold and winter sets in, they are on sagebrush. All those moves might be within a couple of miles or they could be 10-30 miles. Depends upon the area.
If alfalfa is available, our mule deer will travel miles to get to it. Especially in the fall in the plains where the range feeds are dried up. That means they'll often bed 3-4 miles away from the alfalfa and travel almost nocturnally to it. Then feed all night and head back before daylight. I see that routinely.
Deer are all different in different areas. But in general, they want to eat well, drink regularly, and avoid chaos and predators, including humans. They'll be in the places you expect them, but they'll also be in places you'd never expect them. That's what makes them fun to hunt and learn about.
