The symptoms are (1) an unexplainable urge to find warm weather, (2) an urge to get off the boat when it snows, and (3) cold feet in the winter. (Just kidding)
Life is full of dangers--the biggest one on the highway. How did you manage to fit 5 group 27s under your cabin sole in a C&C 27? Are you crazy living aboard avC&C 27 in the winter in Boston? I can understand the need for 2 dogs--hope they are big ones!
