Helen Ehrenhofer does a wonderful job of getting lots and lots of people/A's/activities into Model A News. Hear! Hear!
As to the question posed about how to get the publication ... there really are three ways. First and easiest is membership. At $38 US, $50 Canadian, and $56 International, it is a shame for a Model A'er to NOT join.
Another way is to live long and watch the classified ads, eBay and swaps. A 25-year-old copy of Model A News can sell for anywhere from $2 to $20 for the early issues with measured drawings of wood pieces. Then, probably finally, you can borrow a copy from a Model A friend. Just don't expect pass-along reading to mean that you get to keep the magazine!
