Any explanation for this one year drop would be speculation but since we're speculating, I can think of a two kids that in my scout troop that swore they were done deer hunting after the miserable weather and lousy opener of 2007. One went back this year and one didnt. Pure speculation on my part but just as valid as blaming HR.
It is not a one year drop in junior license sales , it is 4 years of declining sales. You were thrilled when you thought adult license sales reversed the downward trend, but now you make all kinds of excuses for 4 years of decline in junior license sales.
