Make a Sneak: Use Folds in Terrain
What may look like a bare open field, or hillside, may have just enough 'folds' (unevenness) to make a sneak. Elk manage to get in and out of farmers' fields, undetected, using folds in terrain - and they are big creatures!
Ducks and geese lounge away the day unharrassed in shallow indentations in fields 'just off the road' ...undetected by passersby and hunters alike. So if they can do it - so can we. You might just get close enough for a long shot. Try it - might just work. What have you got to lose?
