We were talking about anti-littering adds they ran when we were kids. The crying Indian and Pitch-in, I won't ever forget.
Today we don't just throw away trash into a can, we separate garbage from recycles and the recycles sometimes have specific bins.
Most folks care but it still seems strange to me that a person would goe to Pinnacles (it's not the party destination as Arroyo Seco is) and hike the trails scattering their snack wrappers, lunch, juice and water bottles allover Mother earth. I really don't want trash cans at trail junctions. Pack it in, pack it out.
I wish there was an incredible add campaign running that would bring conscience, educate, and place value on everyone doing their part. Get an add switching from our streets, beaches and parks, with kids, working folks, public figures...and ending with a few sport and pop-music stars saying "It's my planet, making sure it's not trashed is my job" or some like that to make people think about it.
As far as not cutting trails goes rock and branch barriers seem a possible deterrent, Stop Erosion, Don't Cut Trails signs might work. Or arm Park Staff and deputized Mud Masters with sniper scope rubber bullet rifles.
