In the episode from Season 7 - You saw a what? (Jan 5 1967) Ernie's UFO Moonbeam vehicle. I think the spot where the flying vehicle landed (matted grass and singed burn ring) was next to Mayberry's (The Andy Griffith Show) Meyer's Lake. Now the actual lake was never shown, but the trees look awfully familiar to same same spot where Opie and Andy are walking in the TAGS opening and Opie stops to pick up a rock to toss into the lake.

There's also an episode from Hart to Hart which have scenes on the same road.

Boy, that lake connects a lot of shows. Its very noticeable.

When Jean Peason visits Bryant Park in Season 5, after a long absence, the house she's staying in is the Taylors' residence from TAGS. The front porch is unmistakable.

And later when Steve and the boys visit his boyhood hometown, the sister of his old flame lives in that house. Even a tree or two at the treelawn is recognizable, I can picture new driver Aunt Bee's run in with one of those when the tree trimmer asks her to move her car.

I will definitely check that out. Real cool.

I have been skipping around seasons so it's no biggie watching them out of order.

Here we see Mike Douglas going up the walk to the house that was serving concurrently as the Taylor Family residence on TAGS, as I mentioned, seeing Jean Pearson for the very last time (Season 5 of M3S, "Goodbye Again," Nov. 1964):

Maybe they could have called Bryant Park and Mayberry "sister-cities," but I don't think the vibe was there for the Douglas Family to have lived in North Carolina...!

Cynthia Pepper's acting is very good in that episode, she's convincing when Jean finds out that Mike is no longer on-the-market as her potential lover, crushed.
