I need help....I need a shoulder bag I live in the Washington /Portland area and it rains. (I come from Las Vegas so I didn't have to worry about rain) I don't want a bag I have to worry about. I only own 4 shoulder bags and I always buy totes or satchels. I need help, which shoulder bags should I consider with my PCE. Tell me the great things about the Carly or the other shoulder bags. I need help
