It's definitely harder in the spring but its slowly picked up for me the last month, although I'm still only averaging one a night. I'm having luck either waiting for them to howl and getting within 150 yards, or locating and coming back the next night and setting up close. Pup howls and Den raid have been working. If they howl close then I'll challenge howl back and usually see them in the next minute or so. I'm having no luck in getting them to bust across wide open crop fields though. We were shooting deer last night and had them open up on two sides of us, but couldn't get them to pop into the open. The weekend rain and humidity haven't been helping either. It's about to get real hard for me once the crops get much taller, I'll be waiting on hay to get cut and hammering the cow pastures.
