![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
ohio
'soap box derby state' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ohio that I've seen before include "State of the union" , "part of the Midwest!" , "American region" , "The Buckeye State" , "American state, capital Columbus" .)
