If I have the entire day to hunt, I will hunt all day until I get something. In at my stand within 45 minutes of legal hunting hours and back to the truck just as the last light leaves the sky. I don't like walking back to the truck in total darkness. There have been occasions where I was up and secured in my stand 1.5 hours before first light, but that was because I was overly excited to be in a prime hunting location that week!
