I have some pretty strong opinions, am a bit set in my ways, and I don't think cool temperatures are an excuse to not go outside. I remember when it hit about 40 degrees when I was little and my mom would let us wear shorts with out coats and sweaters. I still think 40 with sunshine is a good day. Kids in this house put their coats on and play in the yard, and I love it. It makes us all happier when our world extends outside of our walls, no matter the time of year.
