You appear to have seen an awful lot of bucks working scrapes... and at the same time ... in the short time you've been hunting. It's not rocket science and critters are like people or dogs, sometimes you feel like it and sometimes you don't.
You're making hunting much more difficult than it should be.
Yeah David....I know you're right. I just love to hear why people think they're doing what they do. To ME....I think they're so random....they're unpredictable. I don't hunt scrapes, anymore.....but I have been fortunate enough to see some worked that I didn't even know were there. That's what usually happens when I'm hunting and see them.
