>How much empty space should I leave when packing for Devcon? What kind and how many goodies should I expect to haul back? I am planning to take a traveller backpack to devcon (one of those that zips open instead of a drawstring like a backwoods). It hold about as much as a normal suitcase. Should I bring a second one?

My conference experience is that I will come back with several new shirts, the binder, the bag (which is why you probably don't need to bring an extra), and assorted CD's. If I start with a totally full suitcase and a computer bag, I do sometimes have trouble getting everything in to come back, but as long as I have a little room in my suitcase when I get there, I'm generally fine. I have been known to check the conference bag as well as my suitcase on the way home. (I'm one of those weird people who actually prefers to check my luggage and let somebody else carry it. <g>)
