Native New Yorkers like myself can usually spot tourists from a block away. They're the ones looking lost as they wander around the city map in hand.

What Tron gear haven't we covered already? If you went out and watched the new flick this weekend and returned home a little bummed, you're not alone. Betcha this Tron-inspired messenger bag will cheer you up.
