Oh my! I never noticed that there is a real "dead zone" between the Pioneer Valley and Pittsfield. Just a few around Pittsfield and, as you have pointed out, no Level-3s!
Looks like Albany has plenty of L2s, but the only L3 in that city is a Tesla Supercharger.
You know, I wonder if the temporary drop in oil prices is partly responsible for the dearth of stations in cities less populated than others. Interesting, especially since my work is always receiving emails from ChargePoint (et. al.) with offers to promote the installation of chargers. I *almost
* talked work into exploring the idea. I've got a great suggestion for its location, too!
