Leominster Police will sit in the parking lots of the various factories along Nashua Street. Most of the time this is at night and they are pretty well hidden, but they do it during the day as well. Also, they will sit in the access road to the radio antenna off of Nashua Street near the Rt. 2 Connector. During the summer months, the bushes are pretty high, so the police are concealed well. I lived in Leominster for 27 years and even though the police have a pretty good reputation, there have been several cops who were more difficult to deal with.
