Well with so many transportation services UND has is it worth bringing a car to und?
A car is not necessary, but it would make life a whole lot better for you. You would save a lot of time not waiting on buses and shuttles if you had a car. A lot of people may tell you to bum rides, but I never liked the idea... I tried to be more independant and not inconvenience anyone else.
I stuck it out for two years (I transferred in as a junior and lived on-campus). I used the UND on-campus shuttle buses, the airport shuttle, and the Grand Forks City bus (which is FREE for UND students - just stop by the student government office at the Memorial Union to pick up a free CAT Prowler pass).
The city bus is nothing spectacular... it leaves much to be desired, actually... but I made it work whenever I could use it. The bus does rounds in either an hour or half-hour depending on the route but it will get you to Wal-Mart, Target, the Columbia Mall, etc. if you plan your trip right.
Another thing UND offers is the Cab Crawler card - $1/person taxi rides between UND and a business establishment during evenings (something like 5:00 pm - 2:30 am... I don't remember exactly). You can pick this card up at the student gov't office as well. Some of my friends and I made runs to Wal-Mart and Target using the dollar taxi and it worked out great.
As for the aviation shuttle, it was working out great until they changed the damned route. I'm no longer at UND, but the route was trimmed during the last month and a half I was there. Some people who lived near the far end of campus got hosed when the shuttle stopped going down to the Union. For what its worth, I even flight instructed at UND part-time and rode the shuttle 95% of the time. Also as gas started getting more expensive, some people opted to leave their cars on campus and ride the shuttle out to the airport.
I think the experience made me a whole lot more patient
