The nature of a trail tells you how fast the deer were moving and what they were doing. Trails that meander through brush that does not compel them to twist indicates that deer are foraging as they go, perhaps looking for a bed site. Deer use roads and cattle trails too, especially in winter. Snowshoeing on deer surveys, I've had resident mule deer adopt my path immediately because my weight compacted the snow enough to hold them up. Waiting for deer is easier than still-hunting along trails, but may not net you more venison.
Some trails lack good waiting places.
Some good stands are difficult to get to or from without alerting deer. Waiting causes your scent to pool, tainting the area. Deer pressured by hunters or oppressed by hot weather commonly shun thoroughfares until after dark. Although moving makes you vulnerable to detection, it brings you into covers not suited to hunting from a stand. Moving also enables you to explore new territory while hunting it.
