One of the ladies I ride with is addicted to going to yard sales. I might have to try it myself. Last weekend she found a set of hard bags that the seller said were for a BMW. Knowing I ride BMW's she paid him the $20 he was asking and brought them to me. Imagine my surprise to get a set of 40 liter Krauser bags complete with cast aluminum mounts and all the bits to mounts them. Granted they were covered in bird droppings and looked like they has been sitting in a trashpile covered in mud but $20. A little sanding and some paint and the mounts went on. The bags took a lot of elbow grease, a stiff bristled brush and some cleaner but stayed pretty watertight throughout the cleaning. There was even two keys!
Now my little girl has some wide hips.
