Heard a small doe doing that this wekend she just kept making that sound I heard her for 10 minutes straight It got to the point I hoped she shup up.(lol) When I shot my buck this year he came to the can after I saw him I was not blind calling. Some of my partners have had luck with blind calling and mature deer. All I get in on blind calling is spikes and forks. So use the can which ever ways feels right.
