11 Days till take off

In 11 days Jason, James, and i will be taking off for our European vacation.  Jason has challenged me to pack only 1 carry on bag for the 3 week trip.  i have accepted and am now actually looking forward to seeing how little i can get away with using while we're there. I will give you a complete rundown of everything that is in my bag.  I'll let you know what things i have to pick up along the way, but i'm hoping nothing.
