For me out West.....its gotta be spot & stalk. I hunt mainly desert whitetails or the coues subspecies and Muleys. The terrain, wind direction dictates every move I make. The deer are very wary and are difficult to stalk to within selfbow range or under 30yds. Most shots are 30-55yds. The best times I have found for stalking is when there's a consistent breeze, enough to ruffle leaves and cause movement. Or when there's moisture on the ground during a slight rain. Not only are they keen at smelling ya you also have to contend with their eye sight. Even harder when there's more than one animal.
In my over-sized fanny pack I carry a pair of neoprene wading shoes/booties. These are excellent for the final 100yd stalk. I don't wear camo, I just never have. IMO they spot movement everytime with or without camo. I've had deer,elk,javelina,turkey and even bears up close and personal without camo. As long as the wind was right and no movement they never once knew I was there. All this stuff about scent-lok this or camo that is a JOKE.
Its confidence, patience and knowing when to step or move and knowledge of the game your hunting is key.
If it takes 30min to silently go around an obstacle it takes just that. Or you could take 2min and risk blowing your hard earned stalk. I take the longer route everytime. I know.....because I took too many chances and have blown stalks more than I care to remember.
