I have been walking the Camino Portugès starting in Porto. I am now in Caldas de Reis. One thing that disturbs me greatly as I walk the Camino is the amount of toilet trash littering the sides of the path. Out of respect for fellow pilgrims, everyone should carry a plastic bag in their pocket in which to carry used toilet paper until they can dispose of it in a proper container. Yes, toilet facilities are few and far between on the Camino. At some time or another, one will have to go in the bushes. But that does not mean you can leave you toilet paper along the Camino for everyone else to see. Sometimes, I felt like I was walking through a giant outdoor toilet. Disgusting.
