ah, you can put it up the day of. People make a bigger deal aboutleaving scent than there really is. Last season I hunted my squirrel dog all the way up to probably the day I started deer hunting. If my memory serves me correctly, I took my squirrel dog out in the morning and went deer hunting that evening, saw deer too. It was something like that anyway. Deer adjust to their surroundings, if you spend time in the woods, you're not going to bother the deer too much. Like I said I run the woods with a treedog, whooping and hollering at him while the hunt. He barks and makes a fuss. And I still got my deer. All my life I've hung stands and then changed them throughout the season. It doesn't typically hurt much in my opinion.
