If your planning to walk through Mass you really don’t need mail drops. There are so many towns so close to the trail and many folks along the road who openly pick you up for a ride. The towns have groceries and all the things you’ll need to get re-uped for another couple of days. However, Towns to see along the trail that I can think of would be Cheshire, Dalton, Becket/Lee, Gt. Berrington, and Egermont. Stopping in Dalton, or I should say, walking through Dalton, you should stop by and see Tom, He’s a host who lives along the trail and sometimes has Ice Cream! He will also have good info for you about whats a head of you on trail. Lee has a Price Chopper and may other emenities, Beer, beer, beer,. And Gt. Berrington (GB) has great music and wonderful food. with a whole foods market called Guidos. They have great produce and specialty prepaired foods that make your belly soooo happy, and an outfitter. don’t know about hostel or motel?
Anyway, enjoy
Goof
