I agree with the being there(regardless of specific time period) makes all the difference.
It only takes 5 minutes or less for an opportunity to arrive and pass if you are there. And obviously without any great magazine articles or books, etc... during the rut if you are out during legal shooting hours anytime that eventis more likely to occur.
The bottom line is how much of your life do you want hunting to consume? For a family person or someone that has another life besides hunting, then sitting all day may not be your piece of cake.
But there is no doubt, that any time spent in the field increases the odds of a close encounter. And time in the field, if you have it to spend means real experience.
