I just watched an episode of Law & Order. How come they never match up the dates with the time of year they are shooting? I would think by now they would correct that. In this episode they state January 4 thru the 6th. They are walking outside in sports coats. This can happen in Jan.
But the trees are filled with leaves. It appears to more like Spring, or possibly Sept. I just think by now they would know enough to use computer enhancement or some kind of background stock shots.
