You're welcome.
There is still some "theming" left that was intended for the original Pop Century-the lake is shaped like an hourglass and is still called "Hourglass Lake"(indicating the passing of time of course) and the bridge between Pop Century and AoA is still called "Generation Gap Bridge"(it did have "signs" on it for the 1900s,1910s,1920s,1930s,1940s,1950s,1960s,1970s,1980s,1990s but they were removed when AoA was built.)
I have always heard that one of the main reasons Pop Century-The Legendary Years was scrapped was because so many of the decades did not lend themselves to "fun theming" with the 1930s being known mainly for the Great Depression,the 1940s being known mainly for World War 2,etc.
