If legal, I would scout sooner than the day before. Even if you sit in your vehicle in the evenings a week or two before season and listen. Bachelor groups have not broken up yet. So, they are still in winter mode. Won't be long before they break apart.
I would scout at least a couple weeks prior and look for scratches. Areas where turkeys cleared the fallen leaves while feeding.
If you bump one the day before season, you've messed up your opening day. The bird will likely return, but not before the next morning.
