Cotton Eyed Joe, whats stopping you from making heads?
I wouldn't bother getting an ME degree if you're just going to open a shop. An ME degree is alot of work. If youre planning on running a shop and going to school I would think you should plan on your B.S. taking you far more than four years. I have a B.S. in Vehicle Design and a Masters in ME, whci h I just finished a little bit ago. I haven't slept for six years, or atleast thats what I feel like, and I didn't try to do anything else during that time period, but go to school.
Just some stuff to think about. When you get to the point where thinking hurts, stop.
