Very minor--just take the winter boots out of the car. Lately our winters have been very mild.

I was surprised that you take the wool blanket out though. Sometimes even in spring/summer, the nights are more comfortable with a blanket. Also, a blanket can be a life-saver if someone gets wet in a cold windy thunderstorm or the like, and starts to get hypothermia--wool is handy as it will still keep them warm if it gets wet. I'm curious--Do you have a lighter weight alternative in the car?
