When its a regular archery day, I like being settled in and ready to go 30 min before light which usually means I like to get to the base of my tree 40min or so before light. If I bump deer walking in, which has been done before for sure, I'll try and get in earlier next time.
On big pressure days such as opening day though, I like an hour ahead of daybreak. In my neck of the woods, deer will be moving early and pushed, hopefully to my nice quiet spot in the woods since Im already set up and waiting
