So far follow up, I did get out yesterday (Sunday). I believe I was able to call in 2 coyotes, but they got in behind me downwind. The area I was hunting had a lot of pressure from other hunters over the years, so I suspect that these Coyotes were pretty smart and well educated about e-callers. I found tracks behind me and this was on the stand in which I used some custom calls from my friend Brian with Crooked Creek Custom Calls. They must have been interested in the new sound from the hand calls and came to investigate. I also found this area to be pretty difficult since most of the sage and bushes were very small, making my concealment difficult. I would guess that more coyotes came in without me knowing as they saw me before I had a chance to see them.
It would appear that my focus now should be better stand setup. I almost want to setup my stand facing down wind so I can see them come in. But I suspect each area has its own techniques. While it was a frustratingly long day out there (got lost actually) I learned some more things and appreciate the knowledge gained from experience. There really is no better way to learn than by trying and failing. I thank you all for your help on this subject.
