I generally like to be up in the tree and setled an hour before first shooting light. The public land I'm hunting this year says that you can't enter the park until an hour before legal shooting light. That would probably put me on stand may be 20 minutes before legal shooting light if I don't rush through there. I will definitely be pushing that hour prior limit if I can. In the afternoons, I like to be setup about 4-5 hours before sunset.
