What is the best way to carry books? I did my first commute today. I rode home from school, about 7 miles. All I had in my messenger bag on my bag was a notebook and clothes. For summer session I am planning on commuting there and back everyday. I will have to be carrying a couple books, a couple notebooks, and clothes. A rack trunk won't fit notebooks will it? Should I just use a backpack attached to a rack? Do backpacks attach very well to racks? I am planning on buying all the stuff I need before the free shipping at Nashbar runs out.
