I was in Grand Forks for about 3 months working at the Air Force Base. The best thing about my time in Grand Forks was the views of the night sky. You can drive 10 minutes outside the city down lonely dirt roads, surrounding rows of endless crops away from city lights and star gaze!
The surrounding area is flat, really flat land. Large mosquitos here, I remember playing golf on the base and having to swat all the bugs before taking a swing. Things get pretty windy and cold here, luckily I was here during summer. Close proximity to Canada, I drove to Winnipeg about 1 hour away.
