Well, you will see a lot of talk on here about how predictable deer can be. If that is so true, there should be a whole lot of people with VERY short seasons. I think they have some habits, but they are also subject to influence from many, many things. Their habits change very easily. The best thing is to study the deer near you, study deer habits (on here and other sources) and then find out what things change their habits (like the first day of gun season).
