Do you think it's OK to throw food out your car window, sans the paper, or the cup, just the food?

I do, as long as it’s not rudely in someone’s yard, or even on the street. It’s not like I eat while I’m driving so it’s not even a question for me, but we often get Sunday morning breakfast from McDonald’s and take it to the fairgrounds and eat it over looking the river. I never eat all mine, so I toss it for the animals to find.

Same when we’re camping. If it’s food I find a spot 100 feet from the camper and pile it there.
I am insane about actual litter though. I have a trash-trash can and a recycle-can for when we camp. I’m crazy about picking up the crap past campers have left. Plastic water bottles out number them all. They wind up in my recycle can along with beer bottles.
Then you’ve got broken glass and all kinds of shit. Makes me crazy.
