Put a cam out, then you'll know exactly what is going on and when. Save yourself the work of relocating your stand or sitting in a stand where the big one isn't moving only to know this after you set up out of range and he disappears after only seeing him that one time. This happened to me and it sucked! I have since bought many cameras and use them anytime I am scouting an area as well as the rest of the year.
The advice above is also good, I assume the same but feel better knowing than assuming.
