A little follow up, I created a mock scrape last week and left my camera out to monitor it all week. When I went out to check it earlier today, I had eight different bucks check the scrape over the course of the week. Having eight bucks check it is a lot for where I hunt. However only one of the eight bucks "scrapped" themselves. They clearly aren't to that point yet, but I'm happy I started a mock scrape, even though its only August yet.
