Here in central CT, we were without power for 8 hours. Back in 2011, I was in the dark for nine days. If not for my ability to access my base, I might have been challenged to take regular showers, or charge my electronics.
During that incident, my greatest concern was watching my gas tank slowly deplete. It was interesting to see how word-of-mouth was important in finding gas stations that were open and selling. I ended up going to Springfield, MA and waiting in line for 45 minutes, but I refueled successfully.
