I rode Maple Springs last weekend. I was shocked at how many beer cans and bottles were chucked into the stream. But it was fairly obvious to me that the debris was not left by mountain bikers but probably by "4 Wheelers" who are allowed to use the same trail. Although you always have to pick the right battle, I have politely ask people to pick up and pack out. I always assume the litter fell tto the ground "accidently" so I draw the person attention to it and explain their are trash cans out at the exit etc.
When I am doing my roadie thing, I assume when I see a GU package on the ground the person meant to store it in their back pocket but missed. I always carry a small baggy and will stop and pick stuff like that up. Doesn't take all that long and hey makes the trail clean and safe for me too. Now baby diapers and snot/pee rags... I leave those thing be. Only so much I can do!
