I might be able to get out after work on Thursday. That would afford me about a 3 hour sitting in view of the rub. I'm thinking I'll sit just inside the timber on the uphill side of the road. That would put me about 30 yards from the rub. Would it be worth it to get some blacktail estrus scent to spray around the tree a bit? Maybe drag a scent pad behind me on the walk in also? and maybe if nothing comes within a half hour of dark should I produce some subtle young buck grunts or a doe bleat?
