There are more areas that are time specific in the northern NY zones....Where there is a lot of agriculture or a larger population density, the deer usually will go to feed on one trail and might travel a mile or more and return to bedding areas on another trail.
Plus with fewer food sources that are large, a whitetail will eat a little and move on to another. Unlike a large corn field, where they may spend the entire night feeding. Add to that smaller pods of deer and you are going to have to work on finding where they are today....and try to pattern them.....they may not be there again for a couple days...when they work back to it.
Plus hunting pressure added to that may just change times they move....Here a little pressure and they pattern us well...they stay out of the area until they know we aren't there....Try changing it up, and sit your stand from 8-1 one day....you might find they are just coming through after you normally leave your stand.....
