I almost always pick up littler I find on the trail.  Usually lightweight, so it goes in my trash bag which contains my wrappers, etc.  Occasionally you will find something worthwhile. I still posses a Buck 110 I found at a trail campsite in Arizona.

Of course, as an archaeologist, I am always looking for traces of past human activity.  You might consider that in picking up trash, you are removing evidence that will be useful for future students of the past....
