Hi Liz,
It appears you misunderstood everything here so I’ll break it down.

The “joke” is that people always call it “Rockville” and they say that North Bethesda isn’t real. Not that North Bethesda is a joke and I’m not saying that, so I believe you have misunderstood.

Calling the portion of Kensington “super odd” is because if you look at Kensington’s boundaries on a map, there’s a square that’s not attached to the rest of Kensington. That’s super odd because most towns don’t have random ancillary areas that aren’t attached to the rest of the town.

Finally, while the boundary goes to Rock Creek Park, and while the map shows that, most people generally DO view that area as Rockville.
