A lot of folks don't do it in the spring. But I am a big proponent of marking my tree with blaze orange. I carry a roll of blaze tape. It's easy to tear off a piece, or carry some precut pieces in my pocket, and tie them to a tree before I sit down.
And it's easy (and cheap) enough to yank it down when I move. I also wear the pieces I've pulled off the tree on my vest when I am walking out of the woods for the day.
