Depending on where your located, it may be a little early for strut zones. Toms like wide open fields to strut in so they can be easily noticed. When it is early like this, I look for field tops and open fields, make a note of them, then check them closer when the season gets a little closer. Even though you may find one strutting here and there, it don't compare to what it will be like in a month or two when just about every field has a strutting Tom.
