I just got the troubling recommendation from my chiropractor: that I should stop carrying (or more accurately) lugging my teacher bags around, and instead start using something on wheels. Does anyone have something attractive on wheels to suggest, not too heavy, preferably vertical orientation? I ordered a beautiful McKlein LaGrange bag, but it was 9 pounds, too much to lift in and out of the car. Under $500 would be great. Thanks for your suggestions. Suzi
