Edited sentence: Maryland Public Broadcasting was no different, and the original master tapes to "Hodge Podge Lodge" were almost all wiped....Maryland Public Broadcasting offers some of the surviving episodes on DVD, and their description is, "The 30 remaining......" which would indicate that out of over 760 episodes, they destroyed all but those 30....whether or not any additional episodes remain hidden in network affiliates' archives is presently unknown.Unfortunately, a practice called "wiping" (taping over existing shows to save tape & storage costs) was a very prevalent practice prior to the mid 1980's
