I put some mock scrapes in about 3 weeks ago, this weekend found a rub line right along the trail with the scrapes, camera took a pic of two 8's and a nice 9, actually got a pic of a 5 and 6 sparring just to the side of a mock scrape. This is the second year I have used the Buck Fever Synthetic scents and they work great. Only found the rubs along the path of the scrapes, but didn't see any others, figure the scrapes got them worked up
