Okay............My class is going to Pennslyvania (Pittsburg) in April. The ride from our town is about 3 hours there and back. I need a bag (not a backpack) to hold my stuff (stuff to do on the bus-ipod, cell phone, psp...etc.) IF I get my speedy, should I take my Speedy with me?? Or should I use my Juicy Knapsack or something else??
