Lesson 2: Scrapes start early. I take most of my summer pics over mineral licks (legal here in MN), but as fall progresses I switch to scrapes (mock, real, or a combination of the two). My trail camera pics show that bucks readily hit those scrapes as soon as they shed velvet, and that activity builds until the late pre-rut. If you're not getting cameras on scrapes by October 1, you're missing a big boat. Peak scrape activity this year, according to my pics: October 10-24.
