I have hunted them sporatically for years. Around Ohio the populations seem to be up quite a bit. Used to be quite a few crow hunters, but rarely see any anymore. I still have my Herter's crow call I got about 42 years ago, along with 6 crow decoys and an owl decoy. Used to work great, but I guess so many people took it up it grew less and less effective. Like dove calls and wood duck calls I guess.
