Julia Hollenbeck of Wheel Me On has written a piece called Lightweight Shutterbug Travel. Here is an excerpt:
Winter travel can certainly add the extra luggage, (depending on where you are heading) with a lap blanket, coat, sweaters, and boots for outdoors and of course all the comfy things for indoors. Soon your luggage adds up to three or more suitcases or one gigantic case with a tote you hope someone will help you load and unload.
Now summer travel is not as difficult, and can easily be accomplished, with just a couple of suitcases. Regardless of season, traveling is a real hoot and probably a strange sight wheelers might make, after adding a briefcase or laptop hanging over the handles on the wheelchair, squishing the backpack beneath, and camera equipment dangling from the side. Whatever you do, just do not get out of your wheelchair until someone starts unloading your "equipment," because the extra weight could tip the wheelchair over backwards once you leave your seat.
