Depends on where I plan on hunting.. If I am hunting in the woods I will wait till I can see to walk in without a flashlight, that way I can slip in quietly. If I am hunting an open area where I can see or know I have a clear path that I can get to the stand without a light then I will go about 15-20 mins before legal shooting light.. I also will wait longer till about 9 AM if the full moon was out the night before.
