theres a good chance he come sneaking back through the same area.
Had this happen the other day. Me and son were on 4 wheeler and jumped up a nice buck in the field. When we hit the trail in the woods we got off at the creek to mess around, and the buck came back and stood in the edge of the field watching us for about 15 min. Then trotted off.
Could still see him in the wood line tho.
