The Middle States
The middle states are not considered North or South. The interesting thing about the middle states is that there is not a huge influx of tourists in the summer or winter, but here you will find seasonal employment any time of year. You can work in amusement parks, Christmas tree lots, ski lodges, water rafting companies - and the list goes on and on. You may have to scout more diligently for a job, but you will work with more locals - and they are about as nice a bunch as you can find.
Yes there are states (Washington) in here that are farther north than some states I have designated at "Northern". This is because these states are more temperate in climate - don't get in a twist about it, just go find a job ;)
