I remember on a trip to the coasts--in Maryland, I was a 'westerner' and in Washington State I was an 'easterner'.
I guess it's all relative.
Are you sure you need the piece that you left at home? Some computers have the slots that accommodate camera cards--when I first went digital, I downloaded using the USB cable...right up until the day I finally 'saw' the slot for the camera card in the body of my PC. I'd been looking at it for about 3 weeks before I realized what it was for.
It's just so much easier plugging in the darn cards!
