I'm always torn with things like that. While i have quite literally never seen a random cart around because people put them back over here like 99.9% of the time. But i live in a small town with only 800 people, it's nice, quiet and clean. But there is (presumably) one guy who throws out his McDonald's trash out of the car window every other day. It's like the most beautiful scenic route up to the village and just like the grosses food in the grossest brown bag by an absolute douche bag laying around. I often think i should just take it home and throw it away. But then he drives by the next morning it's gone and you become the private garbage collector to the biggest scumbag in town.
