There's probably a lot of them you don't see, especially the huge ones. That's why camtrakkers are so popular.
Was watching a very nice, 150 class 10 pointer make his way out into a soybean field near dusk last week. Thing is, he kept stopping to check out his backtrail, looking back into the swamp he came out of. I kept looking, watching for an even bigger buck to step out. I never saw anything, but the way that buck was acting, it was if there was a bigger buck in there waiting for it to get dark.
