[HELP PLZ!!] I'm having a little problem setting the default value of a property

[MrPolite]

ahem, here's the property:

Private DEFAULT_FONT As Font = New Font ("Arial")
 
<DefaultValue(DEFAULT_FONT)> _
Public Overrides Property Font() As Font
        Get
            Return mFont
        End Get
        Set(ByVal Value As Font)
            mFont = Value
        End Set
    End Property

It says that DEFAULT_FONT has to be a constant expression, but I cant declare a constant of type font.
What should I do? I just want to have a default value for the font property
