Looks like a few guys read your post, but no one wanted to offer an opinion. Peak scraping should be just kicking in about nowin your area. According to your state biologists peak breeding shoud be Nov. 14-16, so things are right on schedule. This is normal activity at this time of the year.
I'd not set up a dripper in the scrape, I'd set one up closer to where you think the buck is coming from. Dig up the ground with your rattling racks or a stick, pour a bottle of #1 Select Estrus or Special Golden Estrus from Wildlife Research Center in the scrape, pour a half bottle of Active Scrape in the dripper, put a little forehead scent on the overhanging branch. And hope for the best.
If you have more questions, on deer, elk, turkey, ducks or geese, post a NEW topic addressed to T.R., or e-mail me direct, and I'll try to help.
