filthy!!! She has to put it on the floor of the bus, which is gets covered in snow and dirt from the other kids' boots before her. Then, her boots end up resting on the bag and she has some nasty footprints. The stains are that nasty black mixture of dirt, snow and ice melter. I don't think I can toss it in the washer, so I've been scrubbing. And scrubbing. Any suggestions? by the way, this is Duckie's second backpack since September, she tore the bottom corner by dragging it into the school rather than carrying it. Also, can I expect her to continue to go through backpacks at breakneck speed? This would be handy to know so that I could stock up while they are on sale.
