Leave No Trace
You never want to litter, so plan to pack your trash out with you when following Sophie's Flat Trail. It can take plastic-coated paper, like found on the outside of many water bottles, up to five years to decompose while it can take an aluminum can up to 100 years. Likewise, it can take a tin can up to 50 years to decompose and a glass bottle 100 years. Therefore, you should pack out all your trash.
