I agee with you cuz on all four
Overseas I was told "Yankee go home" so you are very right on no.1. Growing up I thought anyone above Tennessee as a Yankee. It wasn't until my son married a girl from Illinois that I learned the difference. What I don't know, seriouslly, is where is the line between the midwest and the east. I would guess the Ohio/Pennsylvania line.

To get the WBTS into this, one of my relatives wrote home something to the effect - today we were up against some boys from the midwest, those farm boys can sure shoot straighter than the Yankees."
