For situations when your phone battery might run low, it's great to have one of those portable lithium ion batteries that you can plug the phone into. I got one before a trip a couple of years ago to keep my tablet charged in case my flight was delayed; didn't need it then but I used it last summer when I was listening to Cape League baseball games on my phone. They really come in handy and are small and light. And not expensive.
I didn't realize that Walden Pond was in your area. We are looking at another trip to Massachusetts next summer so I will add it to the list of possible places to visit.
