Cloudy and cool on the way in. Rain on the way home. Today was my first ride with a pannier (single on the left side). I've been using a backpack. I was worried about weight distribution but it was not a problem at all. The only tricky part was when I got out of the saddle going up a hill. Different ball game with the weight all on one side on the back of the bike. It was great to ditch the backpack.
