Default Empty Option for MVC dropdown menu

Question

I have the following DropDownListFor that displays a list of states for the user to choose from. How can I default the dropdown to be empty. It currently defaults to the first state in alphabetical order ("Alaska")

@Html.DropDownListFor(m => m.User.StateID,
    new SelectList(Model.User.States.Where(filter => filter.Active && (filter.CountryID == 1))
                    .Select(item => new
                        {
                            ID = item.StateProvinceID,
                            Description = item.Name
                        }),
                    "ID",
                    "Description",
                    Model.User.StateID),
    new { @data_bind = "value: user.StateID, enable:!isSiteUser()", tabindex = "10" })

I figured out that one of the posted questions did have the correct answer for my problem. I was just trying to do use it incorrectly. I was adding "string.Empty" to the wrong location. This is the solution.

@Html.DropDownListFor(m => m.User.StateID,
new SelectList(Model.User.States.Where(filter => filter.Active && (filter.CountryID == 1))
                .Select(item => new
                    {
                        ID = item.StateProvinceID,
                        Description = item.Name
                    }),
                "ID",
                "Description",
                Model.User.StateID),
                string.Empty,
new { @data_bind = "value: user.StateID, enable:!isSiteUser()", tabindex = "10" })
