With some does, somewhere, almost always in heat, extending the use of estrous doe scent makes sense. More important than these artifices are the places where you use them. Joe Deerhunter has to make some tough tactical decisions during a drizzle rut. Conventional wisdom holds that the bucks are off chasing does most of the time and not at home very often. During a drizzle rut it is very difficult to determine when the hunting is hot and when it's not.
Indirect evidence is the best guide.
Watch the scrapes. When they are kept clean and fresh, hunt nearby buck cover and trails. A well-tended scrape indicates that the buck is at home waiting for company. When the scrapes go dead, head for the thick margins of doe feeding areas, buck-doe trail intersections, and other areas of high doe usage. Untended scrapes are signals that enough does are in the mood for love to get the buck out and about.
