Someone mentioned getting apples from in from of a hotel; in reading about that has reminded me. My sister-in-law saw apples growing on trees in front of the local Taco Bell. She asked if she could pick them and was told to take as many as she wanted--I think she said that she stripped the trees. She made apple pie filling, applesauce, and apple jelly, plus her family had all the fresh apples they could eat.
Some of you have mentioned chokecherries: a few years ago, I drove up a close-by canyon and found chokecherry bushes loaded, so made lots of jelly & syrup that year.
