Cain, Seat and Bag (all in one) Look what I just found! This would be excellent for shopping or traveling. http://www.walkinbag.com/about/testimonials/laptop-rolling-tote-review-jetcart @ Camas, When I go grocery shopping I do use the little electric carts. I actually think they're fun to ride. Makes me feel like being in bumper car as kid. I actually chose the places I preferably shop by, do they have electric carts?
