Well, in a way he's right. Scrapes are territorial markings. A buck is basically saying that "everything inside the scrape line is mine. I am the dominate buck. You other guys keep out." Isn't that why bucks make scrapes?? The fact that does come along and mark them also only says "Hi bigboy. I'm here and I'm ready." At least that's that way I always understood it.
Sounds to me like the boy needs a couple of days in the woods during the Elk rut. Let me step in a Elk Scrape and then say they have nothing to do with females. Aw well, Some folks just view stuff differently.
