One thing is for certain, you will never know untill you try. There are so many factors that could influence the out come. How hungry the rabbit are, how far the stray from home when it is well lit by the moon, how mutch rain we have had in the last few days. The list is endless. I don't think anyone can work it all out, but just by going out you can learn enough to give yourself an edge.
Every area is different, what works for me may not work for you and vice versa. There is only one way to find out, get out and give it a go.
