Bearing His Cross

I see this guy from time to time, not everyday but often.  Today again, there he was, all day long with his cross waving at people. All day long.  Does he have a right to spend his time however he wants?  Of course.  Does he have a right to express himself?  Undoubtedly.  Does he have a right to do it here on public property?  I am less certain about that.  But none of these things are what went through my head today.
