I have about 3/4 of a mile of road shoulder to clean. This is what I find, in order of volume:
Beer cans; soda cans; beer bottles; empty cigarette packs; pint bottles of Seagram's 7 (once I found an empty gallon bottle of vodka); scores of those plastic "Big Drink" "car cups," plus their tops and straws; paper and styrofoam trash from Mickey D's, Hardee's, BK, DQ, KFC, Jack's, White Castle; styrofoam coffee cups; tins from chewin'-tobacco (I thought everybody was too smart nowadays to take up that habit!); chip bags; candy wrappers.
And that's the stuff they aren't too ashamed to throw out of their cars. That's America, seen from the angle of those who clean your road shoulders. I hope you'll all have just as much fun at the CAT-scan center!
