By way of Elder Son's writings, I learn that friend Don Gwinn's old blog, Armed School Teacher, is no more. If you have that site bookmarked and click on the old link, you'll find the entire site has been taken down. I'm happy to pass along that Don's fine efforts may now be found at Push the Pull Door. If you haven't read Don in the past, do yourself a favor and check him out.
First, though, read Matt's blog on the topic. Be sure to click on that first link, I've written, for an excellent introduction to a truly fine man, his family, and his other, subordinate, interests. I've "known" Don for about nine years, both of us serving on the staff of both The Firing Line and The High Road firearms interest boards. Though we've never met face-to-face, I believe you can learn A LOT about a man, reading several thousand examples of his writing.
It may seem a little strange for a senior citizen (memyownself) to write about one of his heroes who happens to be considedrably younger. Well, that doesn't bother me one bit to echo Matt and say: Don Gwinn is indeed a hero, and I'm pround to call him a friend.
