I often hear people at this time of year say, spring is my favorite season. I understand that for many this comes after months of gray, sleet-filled days, snow or slush on the ground, cars and leather boots ruined by over-salted roads. Months of seasonal affect disorder usurping our daily routines, houseplants barely hanging on in dimly lit hallways and the freezer and cupboards emptied of stocks, stews and the dilly green beans of last summer.
