I bought a couple of book's from NAHC about Whitetail's. The book's are a collection of article's written by Whitetail expert's. One of the article's cover's a study on the effect's of weather on Whitetail's. Here's what it say's about Barometric Pressure. Whitetail's prefer a moving barometer to a steady one, and they move about more, when it's rising, than when it's falling. If the barometer is neither rising, or falling, however, they show a slight preference for a steady high reading, over a steady low one. The author's name is John Wooter's. This was an idependent study, based on his own record's, and observation's over a 15 tear period.
