Alright I have a few questions since this is my first bow season and I've never used scents or calls

1. How do I know when the rut is coming? Stupid question, but never being out in the woods to see it what should I look for?

2. Our bow season starts in September in Wisconsin, what calls/scents should I use during early season? Just prior to the rut? During rut? Post rut? I'm looking to pick up some sort of call because I think that'll be part of the fun of bowhunting but I need to know what to look for

3. What is the "best" time to target big bucks? Is it pre-rut or during the actual rut?

4. How long does the rut usually last?

5. Are cover scents worth it or does good old fashion scent elimination work alright too?

I think that's it for now but thanks in advance!
