Looking into purchasing a new bag for school. I have a very high quality bag, but I'm trying to elminiate as many external visuals of my past as possible, and carrying around a digital camouflage backpack doesn't help with that goal. How much stuff does the average vet student carry? I'm currently planning for my tablet (about 4lbs), maybe a couple of books, and assorted pens, pencils, and backup notebook. Since my transportation of choice will be two wheeled, I need to keep the load light and tight. I'm looking at bags by the designers with which I'm most familiar - Camelbak and Blackhawk. Anyone have suggestions for a good, rugged bag that will do well in a harsh enviroment?

I find that I definitely need to keep anything fabric-y off of the floor and in some storage area like a closet. For some reason in our previous apartment the cats never peed on things like they were in this house...but there was a new cat in the new apartment...I believe she was the culprit.
