My advice to you Browny is to do what makes YOU happy. Seems like at this moment going to UND and majoring in AVIATION will make you happy. While many on here have valid points, you have to live your life for you.
If you were my son, I would say to go to UND, major in aviation and attempt to get a flight slot in the USCG afterwards.
There are many unemployed people with MBA's, law degrees and engineering degrees. There are also people with said degrees that are gainfully employed and miserable as all get out. The grass is always greener. So, once again, do what makes you happy.
Keep us posted
