No, It's not just you. I have seen endless sightings during summer and early bow season and when it came time to hunt them, they were gone. I'm not sure in some disease came through or trappers are in higher numbers or coyotes are killing the fox. I have no idea, But in my area I am struggling this year. One thought I was having is the weather and the lack of harsh weather hurting us. Fox don't really have to risk danger by coming into a distress sound when they have all the food they want from rodents, rabbits and deer carcasses. I'm counting on a productive breeding season though. Hope things pick up for us.
