Based on my life experience, I would guess you are from the western half or west coast of the US. On several occasions, while living in CA, I was asked where Purdue was. In one case after being accused of being from the east coast, I explained, I went to Purdue,
Him - "Yea. East coast."
Me - "No, you ignorant hermit! Indiana is in the Midwest, in the Great Lakes region of the country, a state away from the Mississippi River and west of the Apalacian Mountains."
Him - "Well, at least you are Ivy League."
I just let that one go. LOL.
LOL! In the west (NOT all the way west) now but spent the last 36 years in LA and FL.
