M.P.
I, too, do not want to throw them away and haven't found a convenient way for me to pass them on tho I have some ideas for you.
When I lived in Tempe, AZ, outside Phoenix, the library took them and put them in a small area in which they sold books and magazines. That was easy. Even when they were closed I could leave them on the dock.
A hospital here in Portland, OR at one time had notices up near the entrance that said that they could use magazines and for us to leave them in a box. The box was gone the last time I was there. Also my Kaiser Permanente clinic had a similar sign. I haven't gotten my rounded up so that I could drop them off.
I have taken some to the YMCA after school day care program at my granddaughter's school. They use them for crafts. And a teacher friend of mine, that has now retired, took them to cut up, also.
