I think it's an easy question. Call your CO if you don't know the rules. Every state has regs for deer recovered the next day, they tell you how many hours can pass, where to check them in, etc. Lots of folks leave their deer overnight if they're not sure of the hit, so the CO's have plenty of experience in this. Just give them a call that night, and explain you're going to finish looking in the morning, they'll tell you what to do.
