I'm a practical person. Take only what you can afford to spend. Buy only what you know that you can't get elsewhere. Such as 'new demo's - Miracle Chalk just floored me at the NQA show), Put a $20 in your wallet to pay for parking and to grab something to eat on the way back. Take your camera so we can all drool over what we didn't get to see. And most of all...have a wonderful time.
