[I will be posting this to a number of schools so my apologies to those who see it multiple times]
The question “do you need a car” doesn’t address the whole situation.  When I went to Syracuse University I certainly didn’t need a car but it did make it a lot easier to go grocery shopping or visit friends’ apartments when we were upper classmen.  Going home for the weekend was a much easier 3 hour drive than a train ride of 4 hours plus whatever time it took dad to get me.  (30 minutes?). I don’t remember how I even got to the SYR train station.  Most of my friends were really happy that I had a car and was quick to lend.
What about here?  Is transit and Uber sufficient?  How far is the Metro-North Station?
             
            
              
              
              
            
           
          
            
            
              Hi! I’m a current junior at Marist and I hope I can sufficiently answer your question! At Marist, you need 50 credits to have a car on campus (and yes, AP/IB credits count towards that!) For the first year and a half at Marist, I didn’t have a car on campus, and was totally fine.  Marist makes sure there are plenty of ways to get around.  If you’re going on a school-sponsored trip, the transportation is always provided.  There are also ZipCars on campus that are really easy to rent if you desperately need a car of your own.  Otherwise, Marist has a large selection of security-approved taxi services that are always ready to drive students for a really good deal (typically only $5 anywhere in Poughkeepsie.)  The Poughkeepsie Train Station is just about a mile from campus, and has both Amtrack and Metro-North.
Cars are obviously a nice perk to upperclassmen, but there are plenty of ways to get around if you’re not able to bring a car.
Hope this helps!
             
            
              
              
              
            
           
          
            
            
              Thanks!  D doesn’t like to drive, I don’t like car payments, and there’s this service called UBER.  Loving places that don’t more or less require them.
