For a yr or so following its cancellation, NY's WPIX (Ch. 11) aired reruns of the 70s syndie LMaD as a strip weeknights at 8(?).
During the 1981-82 season, WOR (Ch. 9) showed reruns of LMaD '80 at 4:30 AM, as well as Pitfall reruns at 12:30 AM for the last few months of 1982, after it was cancelled.
After it was cancelled in 1985, Viacom offered a "Best of (syndie) FF" package to local stations, among them the aforementioned WOR, which aired it at 8:30 PM after the news, and WVIT (Ch. 30) in Hartford, which aired it at 9 AM, followed by BtB '85.
Countless stations aired reruns of the syndie MG, among them the aforementioned WVIT in Hartford, WNEV (Ch. 7) in Boston, and Ch. 33 in Dallas-Ft. Worth.
In 1985-86, its first year of operation, Long Island indie WLIG (TV-55, now WLNY) aired reruns of Pitfall and the Cullen Pyramid...the latter first started as a replacement for the former in its 12 noon slot, but Pitfall was soon brought back, w/Pyramid moved up a half-hour to create a nice hour of programming from 12-1.
And IIRC, a few stations aired reruns of the original Cross-Wits in the early 80s, as well.
