Ok, but the shoes are usually full-sized adult ones!

???

I always figure the shoes were placed on the seat near enough for the child to reach, and they toss one shoe out at a time.......

A lover's quarrel? "Oh yeah? Well, to heck with you" & the shoe goes flying...

I honestly enjoy seeing what those kids do manage to sneak in and what they pull off during their "serious" walks to receive their diplomas.
As for the beachballs on the freeways, it's always upsetting to see the amount of trash that does accumulate on our roadsides. But I would have wonder about them also. And I'd like to share of the one occasion that my DH & I were traveling in California and suddenly came upon what must have been at one time a HUGE bag of those styrofoam peanuts they use in packing. They were traveling along the freeway at for the most part the same speed as most of the cars. Bouncing back and forth, over each other, rolling, bumping each other and this went on for a good 3-4 miles - seriously. Guess we were easily amuzed but we did laugh in the somewhat comic actions of the little peanuts. ;-D

Too funny!

A lone cushion on the road. Someones couch is now trash :( A laundry basket full of folded laundry on the side of the road. ???

Once my DH and I passed by an apartment complex and some woman was dumping her mans clothes out the window, a drawerful at a time. LOL if it were not so sad.

One of those things that make you scratch your head and go Hmmmmmmmmmmmmmmmmmmmmm.

I always think maybe the lone shoe is the result of an accident. Gruesome, I know.

I've always wondered about that one shoes on the road also, kids shoe ok! but bigger shoes????stinky feet (:

that is a good question about the shoes I don't have a answer for it.
