I get to my turkey hunting spot at early 30. My watch has 4 times Early, Early 30, Late & late 30. Early 30 is about 40 minutes before that first ray of light starts to show. If you show up to go hunting with me at Early 32, the truck left about 3 minutes ago. I'd leave my Dad if he was a minute late......................come to think of it, he left me once!
