Even first light, don't expect the deer to be good. Tracked a buddies deer from 7PM to 11PM Sat. night. Came back in the AM and found the deer, meat was loud.
Got down to 45F that night and we found him in water half way. He wasn't puffed up or anything. I took out the inner loins thinknig I would have dinner. Stunk up the house aweful. Fed em to the dogs. Butcher wouldn't take the rest either.
