If you have paid for HVAC services in custom calls.
If your wife calls you on your cell phone to say the baby is crying at two in the morning only to realize she actually heard a duck call being tuned.......Tone board needs some work if that's the case
If you start driving to Kansas City in late January, regardless of where you live.
If you try to re-purpose every new tool you get at work to making a process in call making easier.
If you carry a mic with you to the sporting goods store when you look at calls.
If you decided that buying a call was just too darn expensive and 3,000.00 dollars later, you brag about how little it cost you to make the new shiny call around your neck.
You pull every call you see apart with no regard for another person's tune job.
