Turn the lemons into lemonade. A friend of mine lives on Olive Street. He parks 25 cars on his front and side yard. His backyard is rented to sororities and fraternities at $600 a game.
I live, work and went to college in Iowa City and recently there have been several middle aged co-workers employees of mine who have moved here from other states, town, etc. They feel that they need to clean up the town and save it from the college students. I tell them the same thing... it is the college students town! No one would have a job in this town if not for those college students. So you want to clean it up get an orange vest and pick up after them or create a company that recycles or something usefull. If you try to use legislation it will backfire.
One of my friends kids paid for season tickets by collecting cans on football Saturdays. So find a way to fix the problem yourself and quit complaining.
