Cyclone - Have you ever thought of using a stalking stick. It is used to make a two legged person sound like a four legged animal.

Instead of sounding like: crunch crunch crunch (sound of a person walking), you can sound like crunch crunch crunch crunch (sound of a deer walking). I do this by using a 5 or 6 foot long walking/stalking stick. I generally move it straight up and down while walking slowly, letting it hit the ground just after the sound is made with my foot. Sometimes I will kick it a little forward to make it produce the same sound as my foot.

Have you ever watched deer in a field. They will turn and look in a certain direction. Their ears will turn and listen, yet they do not spook. Then, another deer will enter the field from the direction they were looking. That is how deer react when using a stalking stick. They want to see "who" (other deer) is coming, but will not spook until they see or smell you. If you sound like a human walking, you will spook the deer before you even get close. If you are patient and move slowly, you can get close to deer without spooking them, even in the dryest conditions.

I always use a stalking stick to and from my stand or when still hunting. I have had deer come in to investigate me (along with a pair of coyotes one time).

Anyway, I think this is a little known trick that can be quite effective.
