In the east, there's a ton of tech. Microsoft's second largest campus is in Fargo, and with that comes a lot of satellite companies (vendors, consultancies, etc). There's also nano tech and a ton of biotech here. UND in Grand Forks is well-regarded in the region for its aerospace program, and there are plenty of opportunities in that field. In the last 20 years or so ND has gone from largely agriculture-based to fairly well-diversified between ag, tech and natural resources.

If you're thinking of moving here, though, let me tell you that anything anyone tells you about the winter is truly unimaginable. You need to actually experience -30 degrees to understand it.
