My favorite locator call… well that had to have been hunting right outside Eglin air force base in Florida. Every morning at least one pilot would want to open up the throttle a little bit over our hunting camp… let me tell you, a sonic boom lets you know where EVERY SINGLE turkey is roosting in a ¼ mile area lol
But in lieu of supersonic jets… I like my owl call in the morning and crow call in the afternoon.
