If we'd of had the spring we had last year, this weekend would of been great, but with this late spring the birds are just thinking about getting moving. Last year I mowed my lawn already, this year we're still covered in snow. This early season, I'd use more gobbler calls, just like in the fall seasons. A strutter decoy and gobbler talk should work well since they aren't in the sexy mood yet and still working through the dominance factor.
Good luck in the morning, and I'll chat with you at the expo.
