Just drove through Springfield, MA and got a LTE signal while on I-91 in the south end of the city. I was able to run Speedtest and got 6988kbps down/5470kbps up on the first try, 10352/600 on the second. The signal was likely from the Cross St. tower in Agawam, which is just across the river from the highway. While driving through Longmeadow, MA I was also able to pick up a LTE signal, from the Pondside Rd. tower, and was able to get 2669/354.
