Is there a sound file or something where I can hear this doen properly? My friends do it without a call, they just make the sound with their mouth and i guess it works for them. Does one sound work better than another?

Regarding a drag line for doe estrous, should i make a big circle in the morning before i go in my stand that leads in front of my stand or should i just hang a cotton ball in a shooting lane? If I walk around dragging some scent Im thinking I could spook or jump a buck before I go hunting..

Would rattling be OK to do in the same day as estrous/bleating? What time of the day and how often/how far apart should each be done?

Thanks
