Chris,
Byron South said it best: "While predator calling is not rocket science it ain't like falling off a log either. Your set up or stand will make up about 90% of whether you succeed or not. It's not hard to call a coyote. The difficulty is calling him to where you can see him and kill him before he detects you. When you are hunting wooded terrain he can get your wind, and leave before you ever knew he had responded."
------------------------
Back in that thick stuff, you are bound to spook a coyote once in awhile. Your best bet is to enter the calling area with wind in your face, or in a crosswind. Find a small clearing of sorts, so that when you call a predator you will be able to see him. Set your caller approx 50 yards crosswind of your chosen hideout. Hide the caller in clump of grass, or carry an extra camo head net to pull over the caller. A simple decoy such as a clump of feathers or fur hanging on a string above or just beside the caller can be a big help sometimes. When coyote comes in, he comes in downwind of the sound (the caller in this case) instead of downwind of YOU. Yes you will still spook a few of em this way, but you will also kill your share of the buggers.
