I feel like sled is on the right track but might be coming off a little wrong.
I by NO means, consider myself a pro, but it is my opinion that the "stand" is absolutely the most important factor in the east. With the thick places in the east, that is what makes a Pro. I believe that a smarter hunter, picking a better stand, is what sled is talking about. An experienced hunter will pick a stand MUCH different than a novice, and why they have different results.
Of course there are many things such as talking/noise, parking to close, slamming doors, poor entry that people learn early not to do; but may still not have good results. Set up is the breaker.
First off you need to pick a "stand" that is in the same zip code as at least one coyote. Location, geography, population, ect... dictate that but if there is no coyotes in walking/running distance, they are not going to fly over with Delta /ubbthreads/images/graemlins/grinning-smiley-006.gif This possibility is were most guys hang up and think there must be no coyotes because they didn't SEE any. However, there may have been lots of movement, it was just in the bushes.
Unlike the hunter, the coyote doesn't have to come into view to know you are there. If you give the coyote an opportunity to go downwind yet still stay in cover, your busted ever time & never seen the coyote. Out west, many places have enough opening so that if the coyote moves around much, your at least going to catch a glimpse.
So as you become a better caller & hunter in the east you pick your stands more wisely. You will not set up as to give the coyote an advantage. Giving up a great spot because the terrain allows the coyote ample opportunity to investigate without using his eyes becomes common. Or maybe skipping a setup because the wind was wrong that day. A novice may set up anyway & educate the coyote (making him even harder to kill when the wind is right).
The only thing predictable about coyotes are they are unpredictable /ubbthreads/images/graemlins/smiliesmack.gif. Some may charge in with no care in the world, but the experienced caller knows how to set up to play the odds. Bad set up with 100 coyotes listening still equals poor results. I’d like to know how many coyotes I’ve called that I didn’t see….
They are not plentiful in the east, but if you find a place were the terrain only allows the coyote one place/funnel to come in with cover & wind, you have the upper hand. AAA players find this spot, TEE-Ball players will be running the bases backwards /ubbthreads/images/graemlins/smile.gif I know... I held the bat by the big end a while myself.
