My aunt has been watching Highway to Heaven on TVLand at 4:00 p.m. Eastern. She was wondering about some actors today, so I looked up the episode. I don't know if they are showing them in order, but the one after today's has Lara Parker in the cast list.
So, if they DO go on to that one, it's Tuesday, Aug. 9 at 4:00 p.m. Eastern.
