Have a massive state fair in Iowa for the 250th anniversary of America. Then, each state can have their own state fair during the same time as Iowa and the other states can live stream into the Iowa state fair.
50 set ups in Iowa all in a row in alphabetical order starting with Alaska. One set up in each state connecting to Iowa.
That way, the people who can’t make it to Iowa can still be involved, and the people who can make it to Iowa, can talk to at least one person from each state. (Kind of like the “New York- Dublin portal” art work, but only for all the states).
