well that depends what you consider "retro" lol many of the shows I like are older:

I like the later episdodes of "Madison", and I like "Nancy drew" and "Hardy Boys", an for the kids shows I love Mr. Dressup, and I loved "Fred Penners Place" when it was on, though I have found very few people seem to remeber it lol I have to keep decibing to people like remeber? he had dark hair and a beard, and he carried an accoustic guitar and crawled through a hollow log to get to his little 'place' where he sang songs and such" lol oh and I like "the friendly giant" too and the "flinstones" of coarse! hehe
