Salem State in Massachusetts is in D3. I don't believe they ever had a track team but they had cross country not that long ago. It's gone now. In D 2, Clarion in Pennsylvania got rid of cross country and track for men several years ago as did Pitt Johnstown though UPJ brought both sports back. Lock Haven decided to drop both sports a few years back but the campaign to keep the sports was successful.
As others have pointed out, sports play a different role at small schools who struggle to attract applicants than at schools who have more applicants than they need. This can even be true in D1. My dad's alma mater, St. Francis, Pa., dropped football around the time he graduated. They brought it back around 1980 (or something like that) and are in D1AA because they wanted applicants and found that they'd get 40-50 more male ones, guys who had played in high school and wanted to play in college but weren't good enough to get scholarship offers, every year if they had a football team.
