I do 2 or 3 drags in towards my stand for 100-150 yards with estrus pee. It can be great fun to see a buck strolling along then hit the trail you made and watch him turn and come in. I usually start near my stand and go out in a ray then keep dragging as I go over to another trail and then head back to my stand. This way I have a continious loop with two trails connected together. This way if a buck starts following one trail the wrong way he will be forced to loop back my way.

As far as second rut remember they don' t all go in heat at the same time, the first rut is a little spread out over time. The does who do not get bred will go back into estrus 28 days later. So 28 days from the beginning of the first rut the second will start.
