All good ideas.... Some assisted living places also welcome them.
And when those ideas are exhausted, there's always recycling.....especially at those covered bins found at schools, churches, etc. (at least they are here around mid-Michigan) that reward those institutions for collecting. The ones in our area tend to fill up pretty fast.
The local Lions Club also collects paper for recycling, including magazines.
We (LHS) will accept donations of old RR magazines if they are in good-to-excellent condition and are complete by years. We shrink-wrap them by years, put a small $$ price tag on them, stack them by current periodicals, and gradually they disappear. Guys buy them....so they say....to take on camping vacations, to their hunting cabins, etc., just to have something to read in idle moments away from home.
