Fortunately, gun laws in Kentucky are not quite as restrictive as they apparently are in Michigan. Here, businesses may post a "no guns" sign, but even if they find out you are carrying, all they can do is ask you to leave. There is no legal penalty.
Don't continue to accept your restrictions up there so meekly. The country is slowly waking up to the reality that people have a right to defend themselves, and have the means to do so. Just look at the expansion of the number of states that allow concealed carry and now the movement to pass the so-called "Castle laws" which clarify the rights of a person to defend themselves and their home.
