If I'm not mistaken I believe I read or saw somewhere that antlers can grow an inch in one day. An in inch in one week can't be right otherwise bucks would only get like 15-20 inches of bone a year since they're only growing from around mid April to late August(at least here in NW PA). If I can find any info I'll be sure to post it.
Jason you are right, Tr had a article on it and said the same thing. You can find it on his site.
