I don't know Catman. Maybe Mars and Jupiter weren't quite lined up right, or maybe the moon was in the wrong phase 3 days ago, or maybe the barometer was falling! I think that there are days that no matter how good the conditons seem to be, that we will get skunked. You call all day knowing that there are critters that are probably hearing your calling, and no one shows, then ya start wandering if your calling sounds weren't convincing enough, on and on and on. I can't explain it, but it happens time and again to the best of callers. You could go back to that same area the next day, or a few days later and try it again, and they might run over you. This is just proof, to me, that just because they can hear the call, does not mean that they will come. Maybe no one was home, they were all on a dead cow a couple miles from you, or they had been eating beef, dead cow, and were too full to be interested in the call. Who knows, but, get used to it, this will happen again. Seemingly perfect conditions, sign every where, but no shows. It's one of those things that can't be explained. At least not by me!
