The show is still in production with Marianne Fons and her daughter Mary, they're showing the 1800 series now on most PBS channelsl (Saturday mornings). I understand some of the cable companies have dropped the show.
I miss Fons and Porter, not so crazy about Fons and daughter. Maybe its just me, but the projects just don't seem as interesting - I think I just miss Liz, understand she wanted to spend more time with grandkids.
