Hey, everyone. I wasn't sure exactly where to post this question, but I thought it might be good to put it up to you commuters, who obviously have experience carrying stuff. So, the situation is this: I just bought my first serious bike, a Bianchi Volpe (which I LOVE) and I suddenly was confronted with the problem of carrying stuff. I need something to carry light loads (my U-lock, possibly some books, a flat-repair kit, etc) when going to the library, the coffee shop, or a friend's house, all of which are within 5 miles of my house. What form of carrying would you recommend? Would a backpack be too big? Would a rack and panniers be overkill?
