Welcome to the forum buckman, hope you stick around. I have one property I hunt that is thicker than snot. I, and others, frequently see half racks on this property. In the ten years I've had permission to hunt it I know of 12 half rakcs that have been shot on it. I've never shot one myself, but I've seen allot of them there. I can't say why, maybe minerals, maybe the thick nasty brush, I don't know. But that property has half racks. I saw 4 different half racks there this year and my uncle shot a half rack there that I hadn't seen previous.
