I have seen the same thing here in S Texas over the past two seasons. A couple of years ago they were gobbling their heads off - then all that quit this past season. This year seems to be better than last year, but isn' t what it used to be. I was out on opening weekend two weeks ago and had one walk up right behind me without a sound - he had a hen with him - when I gave out a soft call they were about 15 feet behind me. Then I heard the gobble! IF I had waited another 30 seconds.... well you know the rest.
