I actually do, specifically for situations like this. A short (2ft) CAT5e cable lives in my backpack alongside a small 3-outlet surge protector, spare flash drives, spare battery pack for USB devices, etc when I'm on the road. I frequently work while traveling and don't want to gamble that a misconfigured access point near my gate, full power outlet, etc could cost me productivity. I've occasionally even stayed in hotels which didn't seem to provide wifi (or wanted to charge way too much for it), but, had an ethernet jack on the room's desk.
