I too share your feelings on turkey huntin'. Nothing quite like it. Many times I've left the deer stand bc I heard turkeys.

On to your question. Obviously the Osceola you're going to have to go to Florida. The Rios I'd go to Texas and the Merriams, Colorado (or Wyoming would be my 2nd pick). These are my opinions and are by no means the absolute correct answer. I say these because I have looked into the grand slam and those are the places I'd go.But its too expensive for a poor boy like me. My grand slam will not be in one year but rather in a lifetime (Lord willing) There's a lot of turkey hunters on here that'll give you their choices but that's my $0.02. Hope it helps.

I'd also look into prices of licenses if that makes a difference to you. It would me. That also might help determine the states you want to hunt.

Here's a link from nwtf.org's website that shows all the subspecies' range
