Why the hell would you leave the woods entirely if your going to come back anyway?
There is a 0% of you getting a deer while your driving home, eating at home, driving back to the woods, etc.
I usually sit in my spot on the ground 45 min. before light enough to see (not sunrise) till 9 or 10am, then still hunt very slowly (walk 2 steps, stop & look/listen) till lunch time, eat my pack lunch, continue still hunting till around 2pm, then sit in a spot on the ground 2pm-dark.
