Hey frustrating isnt it, thats why they call it hunting. Here is the bad thing if this is a very large buck and you have messed with his scrapes and he has smelt you he will go nocternal so fast it will scare you, or he has you pegged and knows when you go in and out of woods. Give it a rest let it rain and scent go away then swap it up. He is not big and smart because he is DUMB trust me, mix it up on him, what kind of land are these scrapes in thick,open what let me know. GOOD HUNTN
