The two guys I talked to are personally against this thing passing and they have at least one pretty compelling reason and probably more. One of their fears is that the amount of places and businesses that are posted and have no weapons policies will drastically increase. Another is that this might actually make us lose the SDA law altogether because the number of arrests for carrying in a posted place will go through the roof. (I'm thinking that there may now be legislated penalties for carrying in a private place of business that's posted, though I can't confirm that now as I've not read this 77 page bill).

Many states have simply a permit to carry and they do not have these problems.
Also, the version that the house originally voted on did not include open carry so it will need to be debated/voted on there before it can go to the governor.
