What I learned over the years of observing deer is; if you find a liking branch, make note of where it is, find a good stand site downwind, and be ready to hunt it when the wind is right during the season. I've found several licking branches and watched every single deer that passes it will lick, sniff, or nuzzle it as they pass. When the rut kicks in, those licking branches become scrape sites. That branch is a scent signpost where deer expect to keep track of other deer in the area, kind of like dogs to a fire hydrant. The deer won't be there constantly, but they definitely know where it is and will check it out on the way by.
