I've never been to Ohio. Have you ever been in this state?
Yes, it's that region surrounded by many lakes in the US.
What type of climate do they have? 
They have mild climate. It's funny because the word ohio comes from Seneca language and means great river.
What exactly is the Senaca language? Is there a great river in Ohio? lol
It's an Iroquoian language spoken when the Seneca people made contact in New York. I guess because it's surrounded by so many rivers and lakes.
That's interesting. When did Ohio become a state?
It became the 17th state on March 1, 1803.
