Which is more important to you when setting up your tree stand, being able to see the deer coming before they get in range, or using the tree for cover to aid in not being seen by the deer before you see them? Personally, I've found that I prefer the cover. If I'm pretty confident of the direction the deer will be traveling most of the time, I'll face my stand where I can see the direction where I expect the least travel. Thus, using the tree as cover. I can take an occassional peek in the direction behind me, and I can expect to hear the deer coming most of the time. I like to keep the deer from seeing me until they are in range. Then, with a little luck, it's too late for them.
