Like five-oh said, if you are of normal height or shorter, hunting out of a tree stand with a 68" bow may bring some problems, especially with shots that are close up to you. If you are taller, that gives you more of a verical clearance out of a stand. On the ground, you'll just have to be careful of limbs and your position for shots so as not to jam the tip in the ground or catch leaves or what not. Other than that, 68" shouldn't be a problem.
