A Timeline of the 1920's and the 1930's to get everyone in the mindset of events in history. The exact date of the game hasn't been established yet. If you have a preference, please let me know. But it I've approximated it around the late 20's and early 30's.

I did notice that there is a post that related to the central area:
1929: Air mail is flown from Miami to South America.
There are some timeline posts that may interest individuals based upon their Advanced Class. For example:
For Ace Reporters -
1924: All-electric recorder and phonograph are built.
1930: Photo flashbulbs replace dangerous flash powder.
You may find many more of interest!
Thanks to Mrs.Coe for the resourse!
