I guess you don't have to be a responsible farmer, when everyone else can be a responsible farmer for you.

Just pop the bubbles! A slingshot or even a BB Gun would do the trick. We are talking about cow droppings here, grass. It is about as biodegradable as anything is in nature.
What, do you suppose, do the cattle farmers in the area do with their cow sh!t? My guess is that they don't follow them around with industrial sized pooper-scoopers. The problem was created by the need to build a cesspool for the droppings and the results should have been realized by all involved in this undertaking. So now, after years, there are 21,000,000 gallons of sh!t sitting on a plastic liner, being allowed to compost. Why, this is about as natural having a bird sh!t on your freshly washed auto.
