If you think deer aren't patterning YOU if you take the same trail every time.....then by all means keep going down that path.
I realize very well that a deer will pattern you if you use the same trail every time. They will also smell where you have been on all of your other entry/exit routes. I like moving to different trees too, but I will still use the same general path to get to a different tree. This way, you didn't just leave a "new" trail of scent to a different tree. In doing the different path, you may be pushing a deer further away than before, whenyou had only pushed or altered his/her path only 20 to 30 yds. Deer sometimes will only skirt a stand once they realize it is a spooky place. By using the same trail and only choosing a different tree maybe 20 to 30 yds deeper into the area, you may just intercept that same deer.
