On a recent weekend, Laura Owen of Sadorus did a 1-mile warmup run with her dog along a country road next to a cornfield, plastic bag in hand. In just 15 minutes, Owen filled the bag with trash, mostly beer cans and large plastic and foam drink cups. "I usually don't pay that much attention to what's there, and sometimes if the ditches aren't mowed, it's hard to see what's in there. I was really surprised at how much trash we found," she said.
