Rutgers has some pretty good coverage in NB/Piscataway. About half of Busch has coverage (the half along 18, before it turns into Hoes Ln), 18 between Busch and College Ave has full bars and large parts of College Ave are covered (Just about reaches the campus center bust stop). Someone already mapped a good portion on Sensorly, I mapped some more earlier today but it hasn't updated yet.
Overall 3G is a lot better on Busch as well.
