took a picnic up Provo Canyon to So Fork Park. Walked along the creek after eating and were disgusted to see all the trash in & along the creek. Ended up cleaning up one area with about 2 big trash bags full of trash. I can understand a stray wrapper that gets caught in the wind but there were a couple of full trash bags and grocery bags full of trash in the creek. Come on, folks! We should be able to clean up after ourselves better than that. Both daughters waded in to get to it all and plan on asking if their BYU wards would like to go up and do a service project to do more.
