99.99 percent of all bucks killed over mock scrapes could be killed without all the fuss and muss and stinking up the woods. That's just my opinion. IF the deer are there and you do your homework, slip in, slip out, change stands often... low impact hunting... by the time you finish all that dirt scraping and tree rubbing etc etc... you could have alread had the deer in the truck. Why do people feel a need to make a mock scrape. The buck will make his own if hunting scrapes is your thing. It still all basically comes down to food, cover, does and routes to and from. You figure that out you can kill the deer without him ever knowing you've been there. No amount of "perfect Pee" is going to cover up all that traffic in and out to service your mock scrapes. Why make all that stink and alert the deer. Find the deer, find the food, hunt the wind and weather... dead deer.
