Glen,

Sounds like a hit. congrats!!!
When you say you don't want to report it, you sound like all the geologist and water guys I work with. I support Petra and everything she is trying to accomplish with ear tone theory. I am a geologist and have heard ear tones my whole life. Now when I hear a certain ear tone I make a bet with my colleague, and I usually win. I also let Petra know.
I look at Petra's ear tones as a Doctor. She needs all the data to back up her theory in the future. So when you hear a certain kind of ear tone - let Petra know...

I hope you report your ear tones Glen.

Take care.

Shan
