I guess more than anything, I was just wanting to make sure there were people out there that have encountered the same thing. It's hard to bring up this subject with fellow hunters around my community that I do not know very well because they react like I am a complete idiot. That's probably the main thing. Some confirmation that I am not crazy.

Yes, I know the birds are there. (just being direct, not disrespectful)
The interstate noise is not so bad that I cannot hear anything, but it could affect ability to hear at some distance.

I am not hearing gobbling because they are not gobbling. I know that to be certain, but my question is Why are all the birds never (really... never) gobbling?

Could it be the interstate noise or not? What are some other things that could cause it. Thing is, this is not a subject that would be discussed in any magazine or book because it has to be rare. Judging from the looks I get when I talk about it, it must be.

Thank you for your post. I really appreciate the effort people like yourself make on this forum to answer questions. Hopefully I gave you the info you were looking for. If not, post again with questions. Really do appreciate the help.
