I've found plenty of tools and bungees, a few almost full cigarette packs, a purse with a half oz of grass and a couple hundred bucks, lots of singular children's shoes, children's shorts and pants, a really really nice blown glasa pipe and a steel five gallon bucket full of brandless bars of soap. Seeing it all out in one sentence makes it seem like I live in a really skeevey area.
Every ride, though, there is always at least one article of children's clothing- usually one shoe.
