Here in Connecticut, we would never feed the deer. A recent study determined that 60% of deer ticks in our area carry Lyme's disease. Many people here either have had or still have it. Both of my sons have also had it. If it is not caught early, it can cause serious health problems from fatigue to arthritis to mental deterioration. Doctors here have only recently been good at detecting this disease because it can have different symptoms in different people. You may not see the tick bite and not all cases present with a bullseye rash. One friend who had it and was undiagnosed for more than a year was unable to watch television because she could not process language well enough to understand what was going on. Now after serious treatment with IV infusions, she is somewhat better mentally but can no longer work. New Hampshire probably doesn't have as high an infectivity rate in its deer tick population, but I wouldn't take a chance.
