Probably daily? But kinda just when I get around to it, I suppose.
Clue #3- US Nationals 2016 will be held in state that was admitted to the US in the 19th century.
There were 29 states admitted to the U.S. in the 19th century: Ohio, Louisiana, Indiana, Mississippi, Illinois, Alabama, Maine, Missouri, Arkansas, Michigan, Texas, Florida, Iowa, Wisconsin, California, Minnesota, Oregon, Kansas, West Virginia, Nevada, Nebraska, Colorado, North Dakota, South Dakota, Montana, Washington, Idaho, Wyoming, and Utah.
I still think that U.S. Nationals 2016 is somewhere in California.
