RE: What do you wear ?
I see your problem. The ATV is what will get you. 1/2 mile walk isn't far and I would try to do without that.
On our land we have a cabin that has no running water or electricity (I love that). We have a wood stove that was my grandfathers from the depression era. It is virtually impossible for my clothes not to smell of foreign scents. So I focus not necessarily on scent killing tools, but more on scent hiding tools.
Fox pee, skunk scent, pine scent, white oak scent....anything to distract the deer when he/she gets close. The skunk scent I will drop a few drops from the tree stand if need be. Otherwise I usually drag something along my walk like Tinks 69 if the occasion calls for it.
Best of luck.
