RE: Early season "rattling"
I'll tickle the bones for a little bit and then rake them against some thick brush to make it sound more real.
I'll try this tatic for the first three weeks of the season then by the end of Oct. and the begining of Nov. I'll put a more effort ino it.
It doesn't hurt to use that snort / wheeze call with rattling and stomping the ground beneth your feet , with that combination it really sounds like they are going at it
