on the way in it wasn't to bad, nice sunny, moderate temp, but my messenger bag was a lil heavy and my shoulder was feeling it.

On the way back (which i'm glad i left early, albeit 91F) i saw a un forecasted weather front moving in. So along with the weight of my bag previously i also had another large text book i just purchased today added into the weight of my bag. Well about have way through my commute is started to get rained on (which was fine) but then huge head winds and my left shoulder going numb from the weight of my bag. Which was great. Can't wait to get some nice panniers and a rack to get that weight off my body and also still be able to carry what i would like to school.

17mile round trip today with 30lbs on my back.
