This is a similar question but has nothing to do with private land or trespass. Today's hunting is often limited to game management units with specific boundaries. Animals are frequently pushed by hunting pressure towards the edges of game management units. Often they will move onto the steep slopes overlooking the drainages that form the unit boundaries. It always seemed to me that a great strategy would be to glass and shoot from the adjacent unit across the canyon into the unit where you have the tag. Would that be poaching? Assuming of course you are not shooting across a road, railroad, homes, etc.
