RE: how many gobblers
My best is 5 as well. I was w/i 50 yards of them roosted last year. There is a major highway not far away - everytime a tractor-trailor roared down the road - they went crazy.
Just as it broke daylight, i started w/ some soft yelps and a imitated a fly-down. These gobblers went nuts trying to fly down and get to me first. I had all 5 within 10 yards. I actually had to wait until they seperated a little since we are only allowed 1 in PA.
What a blast!
