Any day is a good day to be scouting.
One way of knowing the Tom population in an area is to go out in the morning and listen for them. The more areas you have the better quality hunt you have as you can move depending on what the birds are actually doing the time of the hunt.The hen has usually an area of up to 3 Km sq., the tom will move amongst the hens and stay with the one that is responsive during that time.Just keep your scouting info current and you'll even know which Toms is good enough to take in a given area.In summary, gas spent driving around looking for good spots are well worth it.
